Question 1
The forward wave is given by Vf = 40 sin (ax – 70°) and it strikes a medium and the reflection coefficient is given by G = 0.6 ∠ –20°.
The wave that is reflected back from the medium is :
Question 2
In a free space (z < 0) a plane wave with Hi = 10cos(108t – βz) ax A/m is incident normally on a lossless medium (t = 2ϵo, µ =8µo) in region z > o. Determine the reflected wave Hr.
Question 3
A right-hand circularly polarized plane wave represented by the Phasor E(z)= 
impinges normally on a perfectly conducting wall at z=0. The induced current on the conducting wall is
impinges normally on a perfectly conducting wall at z=0. The induced current on the conducting wall is Question 4
A plane wave in free space (z <= 0) is incidentally normally on a large block material (μr = 3, ϭ = 0, Ɛr = 12) which occupies z > 0. If the incident electric field is E = 10 cos(ωt-z) uy V/m, then reflected magnetic field is
Question 5
Two media 1 and 2 are separated by x-y plane. Medium 1(z > 0,
) has electric field 
V/m. what will be the electric field in medium 2 (z < 0, 
).
