Question

. Assume a medium with µ = µ0, ϵ = 3.2ϵ0 and a magnetic ﬁeld
intensity:

H = 7exp(−x/3)cos((10^10)πt−βx) z (Am−1).

Determine the corresponding: i) loss tangent; ii) wave length; iii)
intrinsic impedance; iv)

electric ﬁeld intensity. How do the determined values diﬀer
compared to the corresponding

ones in vacuum?

Answer #1

Solve and find the indicated answer:
A non-magnetic dielectric medium has a conductivity of 0.01 S /
m and a relative permittivity of 3.5. A 100 kHz wave propagates
through this medium and its electric field is defined by:
E=31 e- αx cos(ωt - βx) ay V/m
1. Determine the intensity of the magnetic field at time
t = 0 and at a distance of 10 m.
The correct answer is: 0.290 A / m

The direction of an acoustic wave, traveling in a medium having
ρ=1.275 Kg/m3, is determined by the propagation
vector
k=9πi-4πj-15πκ
m-1
If the intensity of the incident wave
is 0.114 W/m2 and its amplitude is 10 Pa, determine: (i)
The wave length of the wave, (ii) its velocity, (iii) its period
and (iv) the power received due to its normal incidence on a
detector of area 50 cm2.
