S11 is the reflection coefficient measured using a vector network analyser

frequency of incident signal. I am doing a sweep from 8-15GHz and recording the S11. What i did is the following, I simulated a material (with known electrical properties) and calculated the S11 for 8-15GHz. Therefore I have the S11 for particular frequencies and their corresponding electrical...

I would like to relate (empirically) the reflection coefficient of a material with a physical property being length, electrical properties etc for specific frequencies. That is why the input of the model/equation will be the frequency and reflection coefficient (at that particular frequency) and...

Hi all, I am trying to obtain an empirical equation/model having 2 inputs (frequency and S11) and one output (a physical parameter) I have done various simulations using CST of the System and now I am trying to relate S11 and frequency to a physical parameter. Any suggestions of how I should go...

Solving 4 equations for 4 unknowns Hi I am trying to solve the following equations using Matlab for C1, C2, C3 and C4. In real fact I only require C1. C1-C2-C3-1=0 n*C2+C3/n+(d-1)*C4=0 C1+b*C2-b*C3-1=0 b*n*C2-b*C3/n-C4(1+d)=0 This is what I have input in Matlab but it seems its...

I have sent you an email but if you prefer I post here, let me know thanks a lot

Hi I am working on a project to do a coil simulation using COMSOL to determine inductance and resistance variations with frequency. I have a CAD file for the geometry but I need help because I am having serious difficulties with the rest. Can anyone help pls? thanks a lot

Hello, I m a student using COMSOL Multiphysics. I have to admit that I am new to this software but it is giving me loads of problems. I am trying to model an eddy current sensor by modelling the coil and a plate (mild steel). The size of the plate is 17mmx17mmx3mm but I had no problem with...
