Q1/In an anisotropic medium, permittivity varies with electric field direction, and is a property seen in most crystals. Consider a uniform plane wave propagating in the z direction in such a medium, and which enters the material with equal field components along the x and y axes. The field phasor will take the form: jaBz Es(z) = Eo(ax + ayeiaßz)e-jßz Where Aß = Bx – By is the difference in phase constants for waves that are linearly polarized in the x and y directions. Find distances into the material (in terms of AB) at which the field is (a) linearly polarized and (b) circularly polarized. (c) Assume intrinsic impedance 7 that is approximately constant with field orientation and find H gand < S>. %3D

This question is about Wave propagation and I want to answer in 20 minutes
Q1/In an anisotropic medium, permittivity varies with electric field direction, and is a property seen in most crystals. Consider a uniform plane wave propagating in the z direction in such a medium, and which enters the material with equal field components along the x and y axes. The field phasor will take the form: Es(z) = E,(ax + a,e¡^ßz)e-jßz Where AB = Bx – By is the difference in phase constants for waves that are linearly polarized in the x and y directions. Find distances into the material (in terms of AB) at which the field is (a) linearly polarized and (b) circularly polarized. (c) Assume intrinsic impedance n that is approximately constant with field orientation and find H,and < S>.
