متن کاملRay Techniques in Electromagnetics GEORGES
Absfracf-The principles of ray optics and, in more detail, some selected applications of ray techniques to electromagnetic8 are reviewed briefly. It is shown how a systematic use of matrix representation for the wavefront curvature and for its transformations simplify the handling of arbitrary pencils of rays and, consequently, the field computations. The same methods apply to complex rays whic...
