Let x and y components of the electric vector of an electromagnetic wave be given by Ex = a₁ sin wt and E₁ = a, sin(@t+6). Show that for 8 = 2nл where n=1,2,3..., the electromagnetic wave is linearly polarized.

Write the expression for the electric field E of a 300 MHz LH circularly polarized plane wave propagating in the -ve X-direction in a medium with ɛp. = 3, µ = 1, and σ = 5 (S/m).

RF Electromagnetics: . If an x-component of the E-field varies as a sine function, and y-field component varies as a cosine function; assuming that the Ex=0.7Ey, what is the polarization of the resultant wave whichpropagates in the positive z-direction. For frequency f, write the full expression for the electricfield of a plane wave propagating in vacuum.

PS:Please make sure to put a) and c) in the correct unit.
