I am starting off with a simple case of lossless dielectric filled waveguide with lossy dielectric segments on it's sides. I did a parameter sweep varying loss and looking at Ez. I am interested in TM11 mode and hence would like Ez to be high. I am using the transient solver to run this. I put in curves at the input and output waveguide (...)
just select the face and set it into waveguide port. you don't need to set the mode just set the harmonic order
Hi Mona7150, You will define the modes number, e.g how many modes are simulated, but what will define the propagating mode (TE, TM or TEM) will be your geometric structure. If your structure is a hollow waveguide, you will not see TEM modes, because the boundary conditions do not allow. Otherwise, if your (...)
Some options: First, increase the number of modes for the waveguide and look at which frequency this mode is propagating. Maybe you can reduce your frequency span. Second, change the dimension of the waveguide! Regards
Hi. Im doing simulations with a patch antenna, fed by a CB-CPW line... And though I thought i knew CB-CPW well... Some doubts have shown up... Your help will be kindly appreciated. I now there are more modes in this structure but i guess the usual propagating one is the CB-CPW mode, from center strip to lateral and bottom ground planes. I alway
Hi, I suppose that your port is a waveguide port... and then the cst meshing need to have 3 meshcells free (no PEC!) to calculate mode, impedance... that means that you have metal or other PEC in this area of the port. Then check your port excitation, background properties and boundary conditions ! Other solution, if
I tried to design a DRA antenna in cst MWS whose file is attached along with.But I am not getting desired S parameters which may be because of ambiguity in applying ports to the antenna.I am applying a waveguide port at the feed line which is feeding the slot. I am supposed to generate TE mode in that waveguide (...)
I am working on mode converter..i have two issues as follows:- 1.how to give a TM01 mode to a circular bent waveguide in cst microwave studio..? 2.how to check on the output different modes coming out of circular waveguide in cst. The dominant mode of (...)
Yes, waveguide port is OK..... exactly with small mistake.... try study the attachment. If you want, you can send me your project. I will be there on Monday.
I have simulated conductorbacked coplanar waveguide in cst. However I am getting only odd mode fields and not CPW mode ie even mode. Any Suggestions
Looks like I found some answers from searching the previous threads in this forum: and here (Hash answered me in this thread directly, thanks) Basically I just need to define 2 modes
for ur question 1- the embeded port should be to ground ,i.e.,if ur port at z=20 so reference plane should be -20 u run transient solver not frequency solver as u run time not frequency and that method called waveguide method if u use floquet mode(unit cell solver) u should running using frequency solver
Good Afternoon Everyone .. I Would Like To Know What Are The Factors Affecting The Type Of The mode ( TM Or TE ) Traveling Inside A Slab waveguide ?! And Does The Dielectric Constant Er=10.2 Most Probably Gives A Hybrid mode ?! Best Regards .. Thanks Alot !
Question about the frequency domain solver. When I open up the Frequency domain solver parameters windows, where I can specify 'excitation settings' and such, there is a section called excitation where you can specify the excitation port and mode. I had been using floquet modes for a while, and the mode was labeled TM and TE or I can run all (...)
Im doing my final year project about SIW waveguide using cst..i want to find mode TE and TM in cst...plezz reply immidietly..thank you.
waveguide use when u want to simulate normal incident floquet used for general any oblique angle floquet mode only operate with unit cell as it simulate ur design as periodic structure
Hi all friend, One problem put me on edge for a couple days. I am using cst to simulat ethe Coplanar waveguide. The basic on, dielectric material with constant 9.6 and 350um thickness, 70um copper, strip width 350um & gap 250 gap. input frequency 1-5G background material air, big waveguide port according to the instruction, ( i (...)
I am trying to calculate reflection phase for patch reflectarray and i want to compute the reflection phase using floquet ports. I have simulated the reflectarray structure using waveguide simulator approach and already got reflection amplitude and phase. I am trying to use floquet ports to excite similar TE10 mode and compare my results. Any
Hi, You should set a waveguide simulator with two opposite magnetic walls parallel to the electric field and the other two walls as electric walls. Then, put waveguide ports where you want the plane wave to incide. Regards, Iaia
Hi everybody i am analyzing Cylindrical waveguide using cst Microwave studio. I want to calculate Total Power transmitted and Power loss for a cylindrical waveguide using cst but I am not understanding hw can i calculate it? Plz help me. Thanks
