✦ Synopsis

The scattering of a plane electromagnetic wave b y a dielectric lens which b e h a v e s like a m e t a l reflector is considered. A t short wavelengths, t h e leading t e r m of t h e b a c k s c a t t e r e d field c a n n o t be d e t e r m i n e d entirely t h r o u g h simple geometrical optics cousideratimls; instead, it is o b t a i n e d b y means of a modified W a t s o n t r a n s f o r m a t i o n of t h e exact solution. The difficulties t h a t arise in applying this t e c h n i q u e to o t h e r lenses are discussed. § 1. I n t r o d u c t i o n *)
