In: Physics
a plane electromagnetic wave travels in a lossless
environment with physical properties ε = ε0, μ = 4μ0. The electric
field component of this wave is 50 sin (--t - 5x) ay [V / m]. This
wave; the wave will enter a second environment with physical
properties ε = 4ε0, μ = μ0, σ = 0,1 S / m at x = 0 and
perpendicular to the x axis;
(a) reflection coefficient, progress coefficient, standing wave
ratio
(b) electric field and magnetic field vector components of the
reflected and moving wave
(c) calculate the time average of the Poynting vector in both
environments
