I've read about wire-grid polarizers from wikipedia. The article says that waves perpendicular to the wires cannot induce electron movement and hence they pass through with minimal energy loss. On the other hand, waves parallel to the wires are reflected by the wires because electron movement is possible. What I don't understand is two things:
1. why the electron movement doesn't also induce a transmitted wave?
2. why must the wires need to have a separation less than the wavelength?
Thanks
