hi,
i am trying to implement one planar archimedean spiral antenna ( 0.5 - 3 GHz ) with microwave absorber backing (to absorb unwanted waves) over metal plate back ground.but i don't know how to simulate the absorber in ansoft HFSS, should i go for a PML ( perfectly matched layer ) boundary whereever the absorber is located (but i think it has some limitation about the distance it should be placed from strong radiators such as this spiral antenna)OR whether any other method (accurate) is there??
plz share ur views on this matter.
with regards
