Can EM wave go forward back?

19 August 2012

 

This is a bizarre question, but the solution of the EM wave equation goes this way. Take an element of antenna in which an alternate current emits a wave, as shown in the Figure 1. The electric field of this wave is given by the equations (1). Strangely, v is negative for small distance. This is non sense because real waves travel forward, from antenna into space. This is why I said “EM wave goes forward backâ€.
