Question
Download Solution PDFAn elliptically polarized wave travelling in the position Z-direction in air has x and y components
EX = 3 sin (ωt - βz) V/m
EY = 6 sin (ωt - βz + 75°) V/m
If the characteristic impedance of air is 360 Ω, the average power per unit area conveyed by the wave is
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:-
The average power per unit area conveyed by the wave is given by
=
Where η = Characterstick impedance.
Calculation:
Given Ex = 3 sin (ωt – βz) v/m
Ey = 6 sin (ωt – βz + 75°) v/m
η = 360 Ω
Since Ex and Ey are mutually orthogonal vector So
=
Average power per unit Area (Pavg) =
=
= 62.5 × 10-3 W/m2
= 62.5 mW/m2
