Question 1
Electric field intensity of linearly polarized plane wave in free space is given by E = (5ay – 6ax) cos (ωt – 50z) V/m. The phasor from of magnetic field intensity of the wave will be
Question 2
A wave propagating in a lossless dielectric has the components
v/m
H = 1.1
A/m
If the wave is travelling at 
(where C=3
) then 
Question 3
Assertion (A): Time varying electric field produce magnetic fields.
Reason (R): time varying magnetic field produces electric fields.
Reason (R): time varying magnetic field produces electric fields.
Question 4
The field strength of a plane wave is 2 V/m. The strength of the magnetic field (H) in free space is
Question 5
A 150 MHz uniform plane wave is normally incident from air onto a material. Measurements yield a SWR of 3 and the appearance of an electric field minimum at 0.3 in front of the interface. The impedance of material is
