When microwave signals follow the curvature of the earth, this is known as -
For a dielectric-conductor interface where subscript 1 denotes the dielectric, the boundary condition that is NOT satisfied for static fields is
What is the frequency range of VHF electromagnetic waves?
It is required to match a 200Ω load to a 300Ω transmission line to reduce the SWR along the line to 1. What must be the characteristic impedance of the quarter-wave transformer used for this purpose, if it is connected directly to the load?
Which of the following modes is used for propagation of very high frequencies?
The term dispersion describe the process of (1) reflecting light from a smooth surface (2) the process by which light is absorbed by an uneven rough surface (3) light scattering (4) separating light into its component frequencies
Which of the following has the least wave length?
In a certain material medium, a propagating electromagnetic wave attains 60% of the velocity of light. The distance at which the electromagnetic wave (f = 10 MHz) will have the same magnitude for the induction, as well as the radiation fields, is nearly
In a fiber-optic cable, which phenomenon occurs for signal to propagate along the inner core:
Which of the following statements comparing X-rays and radio signals is INCORRECT?
Ez ≠ 0  and Hz ≠ 0 represent which type of mode of propagation of microwaves?
