Hai !! 
😀
We had a special lecture on Radar Cross Section (RCS) from head of CSN iKohza and Research Lab. MJIIT – UTM KL, Prof. Dr. Yoshihide Yamada.
He was a senior researcher in Electrical Communication Laboratories of Nippon Telegraph and Telephone Corporation (NTT) and a professor of National Defense Academy. Therefore, he has a wide experience in antenna design and RCS.
What is RCS 
🤔? RCS is a measure of how detectable an object is by radar, thus it is used to obtain a measure of diffraction.
“Isn’t it interesting? Yes, it really is !
