Hello Sir. I want to design a reflective 3-bit coding metasurface for beam steering. I have already designed the 8 unit cell representing each bit from a research paper. But now I don't know how to check the reflected beam angles. Please help me with it

I am watching from university of engineering and technology mardan Pakistan ❤

can i use farfield array properties to simulate the farfield pattern of whole RIS?

Thank you very much.... It is very helpful video to me

thank you very much.... what the type of port should be utilized to obtain beampattern of the whole RIS?

Can you please make a video on blended rolled edge parabola?

super sir valuable insights

Thank you, please can make a video for the same design that show how we can measure the field pattern of the full RIS to obtain the dynamic beamforming capability .... or kindly, at least provide me a short explanation here....

hi sir is it possible to plot gain vs frequency plot for unit cell array

Where to find horn1.cst?

How to upload CR forms in 3GPP portal

Thanks for the explanation. I just want to make a clerification TE Mode(0,0): SZmax(1)SZmax(1) and TM Mode(0,0): SZmax(2)SZmax(2), right?

Can anyone share prof.Lingaswamy's email id please? The one which he has given here is showing no address.

Can you please upload the next video of this. Cartesian plot etc. thanks

Would you send cst work in this paper

Could you send your email i wanna take with you doctor

This design was taken from my research. You should bookmark my research link

Hello can I communicate with you

There is wrong subtitle in this presentation. Could you fix it?

Such an excellent explanation, Sir. Thanks a lot for your detail. I want to make a model for transmission and reflection purposes simultaneously using graphene, but how do I place the layers of materials with a PET substrate? Should I use Electrolyte along all? Please help me in the best possible way. Thanks Again.

Your videos are awesome sir.. can you please provide me help in my research work on metamaterial?

Hi sir.if we design unit cell for stop band alone,do we have to construct ground plane.

hi sir ,how can i calculate polarization angle in this boundary?

Hello Sir. To get S11, how do I set the boundary? Thank you.

Sir can you please explain how to plot scattered power plot for electric dipole P, magnetic dipole M, toroidal dipole T and electric quadrupole Qe of toroidal resonance in CST

Do you have any video of different type unit cell design for dielectric reflect array antenna?

Sir,Can you share your matlab program?

Can you use a single horn antenna to measure reflection coefficient of a copper plate by putting antenna infornt of copper plate?

Hi sir, for isolation enhancement in the MIMO antenna I have designed a unit cell with dimensions (1.5x10) 1.5 width, and 10 lengths for 28 GHz frequency. Will this unit cell be considered a unit cell because one dimension is large?

Beautiful lecture sir🎉🙏

Hello sir even I few doubts regarding s parameters plot I m getting below -20 db but for entire 1-10 GHz but it should work only for l band.may I kn what could be reasons

HI Sir, Can u please put the name of paper

Sir, I have some misconceptions about the polarization(How to define them), Azimuthal Angle (How to vary them) and some theoritical analysis (e.g., uv analysis of unitcell) etc. Please make videos on these.

Can you please share with us the MATLAB code you stated in the video?

please provide the implemented paper

Sir, can you please give us some insight on Axial Ratio, Normalize ellipticity and UV analysis of unitcell? Your videos are excellent. They helped me a lot to clear my concepts on various things.

Did you simulate the reflectarray with T-solver? I have an offset feed and I got an error saying 'Waveguide ports must be aligned with cartesian coordinate planes for the transient solver' from CST.

After rotating the reflectarray away from any cartesian coordinate plane, it seems that the default meshing does not produce the correct result.

Please give to contact no sir

Thanks

Thank you so much sir

Sir i have a doubt in characteristics mode analysis for graphene based absorber????? Please help me 🙏

Very cool

Hello

Thank you so much for this video. It helped me a lot in understanding the concept of unwrapping the phase. I have also re-simulated many papers and wondered how they got values beyond 360 degrees while I was only getting values between -180 to 180 degrees. I have also watched your other videos, which have been very beneficial for many students beginning their journey in the field of Reflected Phased Array. Thank you for providing such helpful resources

Thanku sir.

Sir can you tell me the books and author names that you have discussed in this video

I am searching job in this field uncertainly i couldn't find because recruiting person expecting hands on experience can u tell me where I can learn

Sir, what should be the free space gap between unit cell surface and the port location? Is it lambda/4, where lambda is the wavelength that corresponds to the center frequency?
