Just one question,
I understand that for an antenna to transmit an EM signal, a time varying Electric or magnetic field needs to be applied to it, why is that so? I mean what's the physics behind it? why can't a constant non varying electric field be used for the purpose? Can you help me out? I would really appreciate it...
