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 and phase of the
equation (1) vary with distance and frequency, that is, monochromatic
EM waves of different frequencies evolve differently in space. In consequence,
the form of the Fourier series is distorted, the traveling signal is deformed.
What is the extent of the deformation of EM signal in space?
