How to figure out TM and TE modes based on dispersion relation?
According to this paper (https://doi.org/10.1063/1.5128679), the dispersion relation of hyperbolic materials is as follows:
then it is said, that he first term in brackets in the equation describes a ...

Does reflection depend on wavelength?
I'm aware of processes like Rayleigh scattering, Compton scattering and pair production. But as these processes treat light as being particles(?) I'm not sure whether they are helpful to understand ...

How are 3 Principle Sections possible in a crystal even when there is only one optical axis and all must contain it?
While studying polarization in calcite crystals, I came across that there are 3 possible principle sections in the rhombohedral crystal. But the conditions are that each section must be perpendicular ...

How can a greater than 1 reflectance coefficient be explained in $\rm SiC$-$\rm SiO_2$ interface?
I ran a simulation using the Transfer Matrix Method to plot the R,T and A curves for a SiC->SiO2 interface. There's a region of incident energies where the |r|^2 I get is higher than 1 and the ...

What formalism is used to model thin film optical coatings that function across a range of angles of incident light?
Thin film optical coatings [0] are atomically/molecularly thin layers of material applied to a substrate with the intent of affecting the optical properties of the substrate. For example, magnesium ...

How is water athermanous?
My textbook says that water is an athermanous substance i.e. the type of substance which does not transmit any incident heat radiations. But how is that true since water is transparent, light that is ...
