Could you give me some references where do that?. I cannot find a good explanation where someone carry on several measurements and predict that the prototype is behaving as a bianisotropic or anisotropic material.
thanks a lot again.
Yes, the aim of my prototype is to use it as an absorber. The cell consist of metallization in the top layer dielectric and ground plane. I would like to identify the anisotropy measuring de cross polarization under different angles of incidence, but I am not sure if this...
Thanks for your quick answer.
I am working with metamaterials so I can have several unit cells the dimension of each are 14.4x13.7 mm and I made a prototype consist of 8x8 unit cells. the frequency range is 5-7 GHz. I don't know how much anisotropy could expect. It could be considered as a...
I would like to distinguish a metamaterial whether it have anisotropic or bianisotropic behavior. Are there a way to do that if you do not know anything about its constitutive parameters?
Hi!
I would like to program new functions to HFSS. For example I would like to add new math functions to get the BW of a trace and I want to define my criteria to the bandwidth definition. I know that there are several predefined functions like XWidthAtYValue but I need to get the bandwidth...
If I suppose that the definition of the S12 is S(FloquetPort1:1,FloquetPort2:1).
The definition of this parameter change if we use a wave port an a floquet port as stated in the pdf "Getting Started with HFSS:Floquet Ports" on page 27, where it is used the S(WavePort1:1, FloquetPort1:2) to...
Hi everyone
I've got a basical doubt in the way FloquetPorts are numerated in HFSS. My doubt is as follows:
If I plot S(FloquetPort1:1,FloquetPort2:1). Am I plotting the S21 parameter of the TE mode or the S12 one??. I know that if you have a symmetric matrix that topic doesn't matter but it is...
Yes I am looking for the response of this structure to an incident wave, but I use radiation boundary conditions to simulate a finite structure. And I use wave ports for example if I want to desgin a microstrip antenna or a waveguide or something like that. I'm not sure if you can use wave port...

Hi!
Plane wave is used when we are dealing with waveguide, it is not the case. For that reason it is necessary to work with plane wave when you are dealing with the general finite problem as far as I know.

Hi!
I am going to add some shotscreen to better understand the model I am using. I began with a finite PEC because the S parameters are known. In the shotscreen of the prototype is possible to see another planar plane in which the parameters S are calculated. The equations...
Hi!
I am trying to get the S parameters from the results retrieved from a plane wave in a finite structure. I try to put a rectangular plane in which I integrate the fields to properly get the S parameters but the results do not satisfy me. I am working on metamaterial absorbers and I need to...
Hi
Yes you are right.
I use normal incidence with PEC PMC conditions and two wave ports with the E field oriented in an oposite directions. My goal was to retrieve the constitutive parameters of my structure but I have a constriction in the most of analysis I found, owing to S21=0 and I would...
Hi!
I have a metal backing FSS unit cell, and I need to apply image theory to remove the ground plane and get S21 parameters and in a certain way calculate the constitutive params.
How can I achive the currents in the lower face are inverse to the current in the upper face and in such way avoid...
