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, 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
Hi could you please share your queries to lingasamyap@gmail.com.

please provide the implemented paper
Hi could you please share your queries to lingasamyap@gmail.com.
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.
Hi could you please share your queries to lingasamyap@gmail.com.
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 🙏
Hi could you please share your queries to lingasamyap@gmail.com.
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
Hi could you please share your queries to lingasamyap@gmail.com.
Thanku sir.
Sir can you tell me the books and author names that you have discussed in this video
Hi could you please share your queries to lingasamyap@gmail.com.
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?
thank you Sir, I got to understand basic working level with help of your video. it is very clear step by step explanation. thank you.
Clearly demonstrated 👍
please what did you copy while the simulation was running?
Please contact me on lingasamyap@gmail.com
any idea on the excitation of the port ?
very informative and good video. could you please guide me on how to design the phase reconfigurable ??
Hi could you please share your queries to lingasamyap@gmail.com.
Good explanation Dr. Dr, can make video about SAR analysis for on voxel human body in CST ?
