Hi, I am currently making an effort to solve a boundary value problem of electromagnetic field.
The problem is as follows:
The region ##y<0## is vacuum. The region ##y \geq 0## is filled with material with ##\mu=\mu_0## and dielectric tensor ## \left( \begin{array}{ccc}
\alpha & i\beta & 0 \\
-i\beta & \alpha & 0 \\
0 & 0 & \gamma \end{array} \right) ##.
If the wave ##\vec{E} = E_0 \hat{x} exp[i(\frac{\omega}{c}y-\omega t)] ## is incident from the left, what the electric field would be?
I tried to solve with boundary condition deduced from Maxwell's eqns, but I coincided essentially unsolvable determinant. I cannot find how the wave would go eventually.(I thought the polarization of the wave would be eigenvectors of the dielectric tensor, but I can get the direction of propagation so that I couldn't use boundary condition) Is there anyone who can give any advice on this?
Thanks in advance.
