GATE 2021: Electromagnetics Rapid Quiz-1 (App update required to attempt this test)

A low loss transmission line of 500Ω characteristic impedance is connected to a load of 1000Ω. Find standing wave ratio.

Determine critical angle for the electromagnetic wave passing through glass to air if ε_r for glass is 9.

For a lossy dielectric material having μ_r=1, ε_r=48,, calculate propagation constant for at a frequency of 16GHz.

In a lossy conducting medium, the phase constant of an uniform plane wave is 1.4rad/m. Now, if for every 2m travelled by the plane wave, its magnitude is reduced by 60%, then determine the skin depth in meters. (Given phase constant at frequency f= 10⁸ Hz).

A 12GHz signal is to be propagated through a rectangular waveguide in dominant mode. Then, determine the characteristic impedance (in ohm) if the group velocity is 80% of the free space velocity of light.

Find phase velocity for a 300MHz uniform plane wave propagating in a material of medium ε_r=2
