wave propagation

Consider a narrow band signal, propagating in a lossless dielectric medium ($\epsilon_r = 4, \mu_r = 1$), with phase velocity $v_p$ and group velocity $v_g$. Which of the following...

A waveguide consists of two infinite parallel plates (perfect conductors) at a separation of 10 $$-$$4 cm, with air as the dielectric. Assume the speed of light in air to be 3 $$\t...

The expression for an electric field in free space is $$E = {E_0}\left( {\widehat x + \widehat y + j2\widehat z} \right){e^{ - j\left( {\omega t - kx + ky} \right)}},$$ where $$x,{...

The intrinsic impedance of a lossy dielectric medium is given by

In the case of ground wave propagation, at far-off distances from the transmitting tower antenna, the Poynting vector is
