A wave that is out of phase
with itself

23 August 2012

I do not think such wave exists. The electricand magnetic fields of plan wave are in phase. But that of the solution of theEM wave equation are out of phase. In the Figure1, an element of antenna emits a wave composed ofelectric field E and magnetic field H. The phase of the electric and magnetic fields vary differently, so the electric field wave slides with respect to the magnetic field wave. For...

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 back”.

Why EM wave equation does not conform to relativity?
1 August 2012

This question is not about real electromagnetic wave. Physical wave does not violate relativity principle and always travel at constant speed c. It is the electromagnetic wave equation that does not conform to relativity. By computing the speed of the solution of the wave equation, we find that its velocity is faster than that of light and varies with distance and frequency. This result proves...

Deformation of EM wave signals
14 August 2012

Electromagnetic wave carries signals emitted by antenna into space. The EM field of a wave is mathematically defined by the EM wave equation whose monochromatic solution is the equation (1). A signal is a time varying EM field that can be expressed by Fourier series which is the sum of monochromatic wave functions, that is, a sum of equation (1) of different amplitudes and wave lengths.

We notice that the amplitude...
