We all have heard of flexible PCB, but what about waveguides?

Imagine you're setting up a waveguide system and encounter a problem: you have two waveguides that need to be connected, but they aren't a perfect fit, and you don't have the resources to fabricate a custom connector. Or, you have an antenna that needs to move relative to your transmitter, and traditional rotary joints just won't cut it.

In both scenarios, one possible solution is flexible waveguides.
