I could not able to figure out the following error
Port 'FloquetPort2': The exterior boundary of the faces for a Floquet Port must consist of pairs of parallel and equal length segments, displaced from each other by an integer linear combination of the lattice vectors..
Please help me out.
I am trying to redo the paper Electric-field coupled resonators for negative permittivity metamaterial by Smith.But my problem is that for the case of normal incidence,i do not know how to choose proper de-embedding distance for correct S21 parameter phase calculation.If phase changes extracted...
I am using a metamaterial as superstate to enhance gain of antenna.When i use 10 pass with center frequency 2.5 GHz for the frequency range of 1-3 GHz using fast sweep i got good result.But when i use 10 pass with center frequency 2 GHz for same frequency range of 1-3 GHz
i got poor result.In...
I am trying to follow HFSS tutorial on Floquet port but i am getting following error messageFailed to solve the problem due to lack of precision. The likely cause is that the frequency is too low..I have attached the tutorial and hfss file both.Any help will be greatly valuable to solve this...
I wish to design a Hilbert Space Filling Curve frequency selective surface in HFSS but i do not have any idea how to make that structure in HFSS.I heard of that using java script or VB script i can obtain those structures.If any body suggest me some thing on that regard then it will be of great...
In the process of retrieving Mu and Epsilon from scattering parameter by following D.R Smith's paper Electromagnetic parameter retrieval from inhomogeneous metamaterials i got unwanted spikes in real part of refractive index .I wish to manipulate meshing settings of my structure under simulation...
In the process of retrieving Mu and Epsilon from scattering parameter by following D.R Smith's paper Electromagnetic parameter retrieval from inhomogeneous metamaterials i got unwanted spikes in real part of refractive index which is as shown .I could not able to understand why i am getting...
I tried the way you had told me and got a result where real part of refractive index is showing unwanted spikes and imaginary part of refractive index is exactly opposite of the paper.I had gone through some of the literature where it has been told that for passive material Re(z)>0 and...
Hi fangjing,what do you mean by index=-1i.*log(eink0d)./k_0./cell_thickness;In Smith's paper no where there is any expression of log,then from where you got this ?
Thanks for your response.After going through some of the literature i got some understanding of it.But now i am facing problem in parameter extraction from scattering parameter.I tried it both in matlab as well as in HFSS but could not able to figure out refractive index n.My magnitude...
I modified my code slightly.Now i am getting probably correct value of impedance z .But still imaginary part of index of refraction is wrong.I had attached my current code.Can some body tell me where i am going wrong?
Thanks,
