In many applications, the continuum electromagnetic (EM) theory needs to be replaced by a discrete theory on a spatial lattice. A lattice EM theory has well-known phenomena not present on the continuum counterpart, such as finite frequency cut-off and rotational symmetry breaking. These may be viewed as approximations of to the continuum theory, but not as… CONTINUE READING
