Hi All,
Looking for some ideas or techniques as I would like to measure the voltage induced on a square metal plate in free space. Its not so much about the measuring equipment but more how I can couple to the plate. I considered cutting a slot in the plate and basically turning the thing into a slot antenna and measuring across the feed point. But I guess if the plate is large with respects to wavelength then the whole thing needs to be covered in lambda/2 slots spaced accordingly, and then all the voltages summed. Then of course this becomes polarisation and frequency dependent.
I'm guessing some form of transformer or loop coupling to the plate is the way to go but I'm not sure how this might be achieved?
Any ideas/input would be great.
Thanks,
Stu.
