Hi all, been doing some low power experiments with a surplus gunnplexer {10.5Ghz @ 10mW}. Q: From the limited information I've come across, is it possible to focus microwaves? ie: a parallel beam and/or focused point? I've seen descriptions of what seem like, essentially, a series of parallel sheets of thin (sheet) metal cut to what would look like a profile of a lens. Am I way off base here? TIA! B
microwave lense?

You can make a lens that will work at X-band from paraffin. Melt some in a curved-bottomed bowl. Remove when solidified.

Bell Labs called that type of lens an Acceleration Lens The signal "appears" to travel faster when between the plates
You can also build a lens by slowing the wave by using plastic or many short pieces of wire as in Yagi directors.
