An electromagnetic wave is described by the magnetic field: where B, a, k and ω are constants, x and y are the respective coordinates and t is time. a) What would be the values of ρ and J in Maxwell's equations? b) Assuming no ...
A uniform electric field is generated by particles trapped by an electromagnetic wave in a transverse static magnetic field B(0). The direction of the field is opposite to that of the accelerating electric field near the magnetic neutral sheet created by both the magnetic field of the wave and...
The variations in density associated with an acoustic wave are shown to influence the propagation of an electromagnetic wave. The variation in electric permittivity of the atmosphere caused by an acoustic wave is expressed by the power density of the wave. Under the assumption that the acoustic wa...
