https://youtu.be/ZWu752tGHrU In this post the following problem is solved based on line integral and stoke's theorem. If A = ρ cos ϕ âρ + sin ϕ âϕ, evaluate ∮ A • dl around the path shown in figure. Confirm this using Stokes's theorem. Solution- See the detailed explanation of the problem https://youtu.be/ZWu752tGHrU
Solve the following Problem. A lossy dielectric has an intrinsic impedance of 200 ∟30° Ω at a particular frequency. If, at that frequency, the plane wave propagating through the dielectric has the magnetic field component H = 10 e-αx cos(ωt – 0.5x) ay A/m find E and α. Determine the skin depth and wave polarization.
