    Its really very helpful video. Could you please also provide the information about the 2D and 3D modelling of the Si-ring resonator? How to find the transmission spectrum for different wavelengths ?

      Thanks for your comment. I'm working on the simulation of such 2D structure, it will be published soon.

    How to download the document of parameters?Is there some website can get parameters of various material matters?

      I uploaded the parameters file of this simulation via this link: mega.nz/file/Ne1RDDQA#Ewi1lRUu-CSX3fyc2Nu1SIQkgAdPsSBMt_eRSRARw6s
      For the various materials parameters, you can use this link: refractiveindex.info/

    sir, i followed the steps but couldn't define Silicon. so cross is still on material. after 8:30 cross has been removed in the video but it couldn't be on my comsol work.

      When you define "Wave Equation 2" select core layer (silicon area) for this feature and also deselect this area for SiO2 in materials tab.

    How to do simulation for transmission spectrum of waveguide? I dont know how to plot it. Can you make a video on fiber optic spr sensor. I would like to know how to plot the spr dip with changing external refractive index. Thanks.

      Yes, I will record a video for this topic in the near future.

    Hi Sir, thanks for this wonderful video👍. I'm working on periodic dielectric gratings and followed all the steps from the video. However, I can't find the correct modes using mode analysis (I know the expected mode profiles). When I added an eigenfrequency step, it successfully found the modes. It seems like the solutions from the two methods don't match. Could this be due to using the wrong periodic condition (I'm using continuity condition)? Do you have any suggestions?

      Thanks for your comment. I really cannot comment about your issue. But some problems originate from wrong boundary conditions. In your case, I think continuity BC is correct, but if you had the excitation in oblique incident you should use the Floquet BC.

    how to do this in hfss or cst? Please make a video using CST too. Thank you.

    • @EMSpectrumLab

      The simulation process is the same, but in CST and HFSS you should draw 3D waveguide structure instead of waveguide cross-section.

    please give a video on the design of rectangular patch antenna by the micro_ribbon(feed line) at 2.45GHz frequency
    (you have to see the reflection coefficient S11 the peak in the frequency 2.45GHZ) with the calculation of the precise dimensions of the patch antenna and how to use the wave guide port in the design of the patch antenna and how to make the ground and the patch by the copper in the HFSS software you want to help me because I find difficulties and thank you for moving forward

    sir how to convert this same structure into 3D and coat different material on top of it

    • @EMSpectrumLab
      @EMSpectrumLab  5 месяцев назад

      You need 3D dimension and draw the waveguide with finite length.

    Thank you for the video.. Can I get some information about Photonic crystal waveguide simulation? Actually i have to measure the group velocity of the light propagating through the pCW.. for which i need graph of normalized frequency vs normalized wave vector
