Question 160easy
A wave propagating in a waveguide has a full wavelength of electric intensity change between the two walls that are fartherapart. It has no component of electric field along the direction of propagation. The mode is
Question 161easy
Electromagnetic wave propagation is associated with two different velocities namely the group velocity (Dg) and the phase velocity (up). In case of wave propagation in free space
Question 162easy
For a lossless rectangular waveguide, the operating frequency is 25 percent more than the cut-off frequency for the propagating mode that is transverse electric in nature. The wave iimpedance in the waveguide is
