Can anyone pls help me how to implement mems capacitive shunt switch in hfss.How to take design parameter and how to choose the air gap and also whether we put excitation or boundary to it in software..pls rply
hi iam new to hfss...i am doing project in metamaterial absorber.i have to give floquet port for excitation...but i didnt know how to proceed...can anyone give some idea...
Hi Shekoofeh, Scattering parameters really only make sense when used to analyze finite arrays. The larger the array, the better, but obviously there are practical limitations. Without using finite arrays and scattering parameters, you'd need a different analysis method. Try looking into Floquet ports in hfss -- they allow you to extract scatterin
suppose i made a structure assigned wave port to it now suppose if the whole geometry is kept inside the radiation box such that the port is also inside.(using hfss) 1. will that be called internal excitation? 2. in order to use wave port without making any change in the radiation box do i need to use pec cap on one side of the wave port. how
I have simulated a 3D EM model in CST (hfss). Then in the Design studio, I have developed a tuning circuit which is fed to EM model. CST then calculates the fields in EM model according to this excitation from the design studio. A similar operation can be done with hfss and Nexxim (by using dynamically linked model and push (...)
hello how can i assign a Wave Propagation Vector K in y-direction, the electric field vector in x- direction, and magnetic field vector H in z- direction, using hfss on radiation box in which my design which i have to analyse is place. Best Regards; Bukero - - - Updated - - - please help me soon it's ur
hey there, is there any option to excite a structure with a static field? Thank you
I have designd an MIMO antenna with Co-axial feed .whether co-axial feed should be within the airbox or out of airbox .Here i have given equal height for airbox and design should generate frequency range for GSM, PCS and LTE i am getting dip only aound 3 to 4 GHZ,that to around -2.25 center frequency is 2.5 GHz.what changes ca
1) You need to make sure the excitation is some sort of incident wave, such as a plane wave. If you have this, the menu under hfss-> Fields-> Edit Sources will allow you to select "Incident". 2) H-Field at what point? 3) No. You can however plot the E-field field along a line by inserting a line into the simulation, and then selecting this line a
Hello Everyone, I am trying to simulate a multilayer structure in hfss 13.0. It is made up of copper planes (PCBs) at the top and bottom and 5 layers of different dielectric materials in between. There are two pairs of cylindrical slots one at the top and one at the bottom, through which differential excitation is to be provided. The differentia
How to connect feed line of an antenna to a point source excitation in hfss? Thanking you.
How to assign Master and Slave boundaries for an infinite corrugated waveguide in hfss without overlapping with waveport excitation?
Hi Members I am trying to excite a simple patch antenna using Grounded Co-Planar Wave guide Structure (GCPW) by the techniques shown below in Fig.1. I do so but receive the error of "Port 1 is assigned to an internal face". Can someone kindly assist me in assigning wave guide port to the GCPW structure in hfss simulator. I have
Hi, I am a student from Panama working with hfss. Currently I am just getting to know how to use hfss. I am trying to implement Terminal excitation but the option is not available even after following the instructions presented in the help section of the program. Help would be much appreciated; please and thanks
I am simulating a four port waveguide network in hfss. If I need to see the field distribution animation when one of the two input wave ports alone is excited. How do I terminate the unused 2nd input port in that case? I am using a driven modal approach
Hi, I am trying to simulate a H field due a current excitation over a copper track and I have a question. When I apply the current excitation in this track, hfss considers only the current over a surface of the track or along all the track, including inside? Because, I believe that even if I select all the track surfaces, it (...)
Hello everybody!!! How am i supposed to do port's excitation of planar slot antenna using slot flatness only? (hfss 15, wave port or lumped?) :bang: Thank you! 125879
Hi, I tried to simulate a CPW resonator with hfss 13 but I get this error message"Port refinement, process hf3d error: Port P1 does not have a solved inside material on either side" So can someone help me to overcome this problem tnx in advance125314
hi everybody, I have designed a loop antenna in hfss, and I want to see its Magnetic field along its axis. I have simulate it in Ansoft maxwell and I obtain its inductance 1.8uH. I have two problems in simulating: 1. what kind of excitation is preferable? I have tried the tutorial of hfss but it didnt give me the right inductance. 2. (...)
hello! I am new to hfss and am not sure how to excite my capacitor structure. It is a cylindrical capacitor (plates along the curved edges of the cylinder). I am stumbling on how to excite it, as I have 3 electrodes. I'd like to be able to have the high electrode at +V/2, low at -V/2 and the guard electrode at 0 or +V/2. Is this possible?
