    Attenuation constant plot in HFSS vs theory at High Frequency

    Hello all, I am trying to simulate an Aluminum Waveguide (40 mm x 20 mm) dimension for dominant TE10 mode starting from near cutoff (3.74 GHz) till a very high frequency (near Infrared region i.e. till 3THz). I wish to observe the attenuation experienced by the said mode with frequency so I...

    HFSS Power Flow Calculations

    Thanks for reply. Can you please explain where from does this value of 1.03887 W comes into picture. When I look at the Edit Sources, I can see that PORT1 is coupling 1W of power. So what is this 1.03887 W? What about the concern that inorder to do Poynting vector integration, one need to have...

    HFSS Power Flow Calculations

    Hi all, I have simulated a rectangular waveguide WR284 in HFSS with the WavePort 1 in excited state and input power of 1W. I wish to calculate the net power flow through input port (read Surface1) and output port (read Surface2). I am using HFSS Field Calculate to find the power flow through...

    [SOLVED] what are steps to see polarization in HFSS v 11 ( plz rpy early) ?

    what do you understand by gainLX plot? are you doing the sweep analysis while plotting the curves with frequency for set theta and phi?

    Magnitude and phse plots of E-field for NRI materials

    Hello everybody, Please look at the following two figures which are labeled as the plots for: (a) E-field magnitude. (b) E-field phase. obtained by the HFSS simulation of negative refractive index (NRI) flat lens using effective medium. Please help me how to plot these? One more query, there...

    Need Matlab code for NRW method

    0k. I got what you exactly doing. Let me know your proficiency with MATLAB. I can help you through the process, but may not be able to write a code, especially. First of all, you must have Four matrix results including Mag (S11), Phase (S11), Mag (S21), Phase (S21) for all the structures you...

    Need Matlab code for NRW method

    Doing good too. Oh..then I am sorry, I feel like it is atleast easier than MATLAB one. Isn't it?

    Need Matlab code for NRW method

    Hi PlanarMetamaterials, how are you doing? What I am talking about is making use of the "output variable" options in the Results section of HFSS. Whatever steps are followed in MATLAB coding, corresponding variables may be created in HFSS as output variables. Please note that unlike MATLAB...

    Need Matlab code for NRW method

    Are you trying to extract the S11 and S21 parameters by experiment ? i.e. with your fabricated prototype, and using VNA? Asked you because the attachments deal more with experimental setups. Well, it is hardly of concern here. You can follow the work of either DR Smith et al or Ziolkowoski's...

    understanding field plots of MNG metamaterial

    For Eigen mode solution of DNG metamaterial-SRR Hello Planar Metamaterials, hope you are doing great!! Please locate the HFSS file of my version of Eigen mode solution file of DNG material. Please note, that it is just for my understanding of Eigen mode simulation. Please Check the U and V...

    understanding field plots of MNG metamaterial

    Hey, I would surely use your great knowledge and expertise and would soon report the eigen mode solution results. Moreover, I admit that my previous posts were quite confusing, but one thing is clear, i am to use SRR array spread in X and Y directions, either in below patch "or" above it, not...

    understanding field plots of MNG metamaterial

    thanks again..but i must admit now i am almost blown off.. Please help me in eigen mode solver, as i have never seen SRR based metamaterial simulation in this mode, which is commonly used for unit cell analysis of EBG. You seems to be pretty well known about Eigen mode solution to SRR unit cell...

    understanding field plots of MNG metamaterial

    Thanks again for reply. No, in the real scenario, i intend to use it in a periodic array configuration by placing it both above and below the patch antenna, in the hope of dual frequency operation and hence compactness (if any possible). My major motive is to just check whether the given...

    understanding field plots of MNG metamaterial

    Thanks for your reply. PEC walls are +z and -z PMC walls are +y and -y waveports are shown by arrows in +x and -x Can you explain how? as they are shown to be in three orthogonal directions. What information do you require for this. the HFSS simulation is done in Driven Modal solution...

    Microstrip Filters : Air ,PMC or PEC side walls?

    @ amihomo, CST works on FDTD (Finite Difference Time Domain) and its also a differential equation approach. IE3D works on Integral equation based MoM. Can you please explain your comment now for not using Radiation boundary condition in here. @ Leon_80 I must say, as per the figures you...
