A uniform plane wave with E = axEx propagates in a lossless simple medium
(εr=4, μr=1, σ=0) in the +z direction. Assume that Ex is sinusoidal with a
-4
frequency 100 MHz and has a maximum value of 10 (V/m) at t=0 and z=1/8(m).
-8
Determine the locations where Ex is a positive maximum when t=10 (s).
2.
The instantaneous expression for the magnetic field intensity of a uniform
plane wave propagating in the +y direction in air is given by
_ _ -6 7
H = az4*10 cos(10πt-ky+π/4) (A/m)
Determine the locations where Hz vanishes at t=3(ms).
對這種題目沒什麼概念..
煩請各位高手指點一下
