hello, PMC(perfect magnetic conductor) is an absolut isolator, right? moreover, what is PML? i couldnt find it's defenition, thank you
Hi all , I am making some test on hfss , I create a dipole antenna on HFSS , and I want to see how react with a perfect magnetic conductor , I have try to use a perfect H boundary in a surface under the dipole , but nothing change ! i do not understand this some one know why is this happening ?
is there anyone who work with solenoid to work with magnetic fileds in near field in CST microwave i am so confused with mesh setting and boundary conditions thank you
Hi, I have designed a single unit cell csrr metamaterial and microstrip patch antenna using CST. I don't know how to combine these two structures together and what port (waveguide/discrete) should I used to run the simulation when they are combined. The boundary condition for metamaterial is magnetic for z axis, electric for x axis and open for y
Suppose you have a 3D system utilizing a Total Field - Scattered Field boundary with a plane wave injection and a lossy dielectric sphere in the center of the simulation box. After the plane wave is injected and interacts with the dielectric sphere, scattered electric and magnetic fields are propagated outwards from the sphere (basic stuff). To
Hi All, I'm simulating a magnetostatic problem involving two magnets separated by a thin copper spacer. The total magnetic assembly is on the order of 10 mm cubed. The magnetization is in the same direction and I use open boundary conditions on all sides. The problem is that I find that the height of the magnetic field zero point (...)
hi, For eigenmode solver, i need the TE and TM modes. Is it correct for xy periodic boundary, and z+- electric boundary for TE and magnetic boundary for TM mode? The results do not seem to be correct.
How can I make the face of a cube perfect magnetic conducting in CADFEKO
How can I simulate a superconductor in maxwell? -boundary conditions? -increase the conductivity and reduce magnetic permittivity? How do i make it perfect E? I need my field lines not to penetrate SC aluminium. Also does maxwell take into account the penetration of magnetic fields through very thin superconductors? And can i plot (...)
hi bannay, i want to understand the physical meaning of the boundary conditions and the cases which i set it to ( open add space) or to ( electric, magnetic, conducting wall and open ) thnx in advance
Dear all, I have simulated some published papers' unit cell structure for getting "s" shaped phase curve using cst mws 2010. I draw the unit cell on x-y plane. Then in boundary condition I use x-min and x-max as perfect magnetic wall, y-min and y-max as perfect electric wall, z-min as perfect electric wall for shorting and keep z-max open for pu
hi Master/Slave boundary are used for periodic structures that go to infinity but pec/pmc are used for structures that are electric or magnetic conductors, in fact if im right, you have to use Master/Slave boundary because your structure is periodic! regards red
Perfect H is a perfect magnetic boundary. It causes the magnetic field (H-field) to be in a direction normal to the surface that it is assigned to. The perfect H boundary forces the tangential component of the H-field to be the same on both sides of the boundary. For internal planes, this results in a (...)
In simulation of split ring resonator using HFSS is it mandatory to use Perfect Electric Conductor (PEC) condition at top and bottom of Air Box where as Perfect magnetic Conductor (PMC) boundary condition at sidewalls of Air boundary of air box.If it is so then why we require to do it and how to do it in HFSS? I had attached one of the (...)
an AMC is an atrificial magnetic conductor either you search for a practical design or you can use the theoritical (Perfect M) boundary as I told you here is a paper that might help you "Effects of Artificial magnetic Conductors in the Design of Low-Profile High-Gain Planar Antennas With High-Permittivity Dielectric Superstrate"[/
Create a material with the correct magnetic and electric material properties. Select a surface where the thin film will be applied and apply a layered impedance boundary condition. Enter the thickness and the user defined material along with the substrate material, ie copper. It is of note that HFSS can only support linear magnetic (...)
If you have a look at the transfer matrix like S12, you will see a peak at a certain frequency. That is the resonant frequency. The boundary condition depends on what you are solving. You have three options, 1) perfect electric wall,2) perfect magnetic wall, 3) absorbing boundary condition. Which of these is a good model for your application?
Hai, in x axis u put magnetic and in y axis u put electric and in z axiz open then one port in the top then u can measure the reflection .
I want to simulate this structure in the rail of an EML(electromagnetic launcher) but I dont know how should I apply boundary condition : electric and magnetic wall can anybody help me? I've many difficults with this problem and I'
I recomend putting perfect magnetic wall on the open bounadry surfaces.
Hi Rancid, As you said electric boundary is analogus to Perfect Electric conductor (PEC). magnatic boundary condition is for Perfect magnetic conductor (PMC). These conditions are useful in creating walls, also for waveguide port. Regards
I can suggest two ways 1. Instead of removing the faces, create two box and substrate small one from large box (considering thin wall in design) 2. Define perfect magnetic boundary on two faces which are open
EM Simulator: given geometry, material, boundary, solve the "Maxwell's equations" for Electric and magnetic fields.
Hello, I was trying to use maxwell SV 9.0 for magnetostatic simulation, but couldn't get proper results. Can anybody do it for me? If possible please do the following paper design in maxwell (Please check the attachment for following paper) : "magnetic Field and Force Evaluation in Open boundary Axis symmetric Structures"by A Lopes Riberio. I
can any help me to make the excitation and boundary condition of this structure on maxwell 3D (v11): this is a loop probe array for magnetic field measurement on pcb. thanks in advance.
I want to redo this article: ?Dynamical Electric and magnetic Metamaterial Response at Terahertz Frequencies? but I have find a big problem in the value of S11 and S21. I plot the S parameter which oscillating up and down. According to article, the sample is a planar array of SRRs fabricated upon semi-insulating gallium arsenide substrate (A plan
1. Additional surrounding space needs to correct simulate antennas problems. It is filled the background material. See the 'Open/Add space' boundary conditions in manual. 2. The bounding box size is overall dimension+additional space in first question. 3. magnetic symmetry plane means that it is: a) geometrical symmetry plane of structure b) ta
you need to determine if it is odd symetric or even symmetric, then put either electric or magnetic according to the required boundary conditions at the symmetry boundaries. I think you will find an example about that in the HFSS manua
Take your model and connect to it another sma in the other side of the microstrip Put WG ports on each SMA then choose in MONITOR menu the E field in the freq. you want. In the boundary put magnetic sym. in the axis that pass thru the 2 SMA and the microstrip. You can add the solder by blend between the pin and microstrip. RGZ
Hi, I met a question , but I don't know how to answer. Someone in my group uses cavity method to analyze a cylindrical dielectric resonator antenna, and suppose all boundary surface as pefect magnetic boundary ( PMB). But it seems it is impossible to get impedance distribution vs frequency but only radiation patterns if this PMB
When the tangential electric field is zero, the boundary is electric wall. Same to the magnetic wall. In cst or HFSS,the Symmetry planes are provided. But whether the wall is electric or magnetic wall,it is based on practice!!!
Hi, guys! Need some hints on following: Imagine you calculate eigemodes of patch antenna (2D In-plane waves) according to cavity model. Now I'd like to calculate radiation pattern. As you know, there are 2 possibilities, electric or magnetic currents.. Currently I'm calculating farfield from electric currents but quite better should be u
Hi, pewang! Please can you post your design here? Will be more telling. "symetry boundary" you mean electric or magnetic wall? We will try to solve it, I ever haven't problem with port impedancies.. Rgz, Eirp
