Spherical electromagnetic wave
WebEveryone knows that an e-m wave is not spherically symmetrical. It is so obvious that those who deal with the subject will use the term "spherical" to describe the next best thing, the … Web27. jan 2009 · Abstract. In this paper, the invisibility of a metamaterial cloak illuminated by spherical electromagnetic wave is analytically investigated based on the full wave Mie scattering model. It is shown that for a cloak with ideal parameters the scattered field intensity is zero, but for a cloak with a loss, only the backscattering is exactly zero.

Make an Ansatz, E = E 0 exp ( i ( k ⋅ r − ω t)) r ^ B = B 0 exp ( i ( k ⋅ r − ω t)) r ^ The wavevector k must be k = k r ^ for spherical symmetry. Now Ampere's law is ∇ × B = i k × B = 0 = ∂ t E = − i ω E which implies ω = 0, so that the field is static, or E 0 = 0.

Webwaves, to the points of the front of a spherical electromagnetic wave gives a distorted picture of the physical reality. The expressions of Doppler effect and aberration, as well as the transformation law of the wave fronts for spherical electromagnetic waves, essentially different from those for planar electromagnetic waves, are obtained.
