Tilted Interface

The element represents the flat boundary between two media having indexes of refraction n₁ and n₂. Then the incident angle of the beam is set via the element’s parameter α.

It is sometimes convenient to set the angle inside the n₂ media as if one would want to set β angle instead of α. However, there is no additional β parameter in the element, as it leads to ambiguity what angle should be considered. Instead, one can give the negative sign to the angle, and it forces rezonator to treat this angle as being inside of the n₂ media and calculate the first angle accordingly.

Warning

The left and the right adjacent elements of an interface element should be either Empty Space or Space Filled With Medium. rezonator doesn’t complain if they are not, but you can get incorrect results.
