simple question regarding hfss

Hello guys,

I want to simulate the electric field in a nano gap caused by radiation (gap is formed between the arms of a nanowire). However HFSS does not allow to simulate the electric field in the vacuum. Can anybody have a suggestion about this?

Thanks a lot

hi,can you upload your model? maybe something wrong with model

put some line or box where you would like to observed the field

Hello,

Thank you very much for your consideration. I have attached my model. The thing I'm trying to do is to simulate the field pattern in the gap at the middle of my model like shown in these pictures.

PS: After two days with no reply to my message, i had lost my hope for help and did not check the web site that i"ve just seen your reply

Thank you vey much again,
Alibey
