Hello everyone,
I have faced some challenge in HFSS. I want simulate two coil . One is transmitter coil, TX,and the other is Receiver coil, RX.
Then RX is placed on the metal plate,so the transmission efficiency decreases owing to eddy current on metal plate according to Lenz's law.
Thus, I want to design the metamaterial to absorb EM wave and avoid reverse magnetic field caused by eddy current decreasing transmission efficiency between TX and RX.
The following is my structure ,exitation and boundary.
I want to take use of equivalent LC circuit of this metamaterial to absorb EM wave.
So, I expect that S13 (transmission efficiency) with metamaterial is better than with metal plate.
But my result doesn't match my expectation.
Here is my problem:
1.How many Lumped port should i assign? Are 4 Lumped ports OK?
2.Whether I have to assign another boundary ?
3.Whether anyone has another suggestion about Exitation because I have no idea how to simulate the absorption of my metamaterial.
So far , I just compare different condition (with metamaterial or with matel plate ).
Thanks greatly much .
I have been confused for a long time.
I need to mention that I take use of this metamateraial structure to realize whether my boundary and excitation is fine.
