[CST] Illumination of nano-antenna via EM source.. No feed/port point?
录入：edatop.com 点击：
I am trying to simulate a cross-slot nanoantenna. The relevant paper is attached.
The design:
The problem Im facing is how the authors were to able to excite the structure? They mention in the paper that " the structures are formed on SiO2 substrates with gold metal patch having no ground, and they are illuminated by broadband plane wave sources from the substrate side normal to their surfaces."
Can someone plz tell me how to excite the nano antenna, without direct feeding, with a plane wave in CST?
Awaiting replies,
Regards
