Abstract
Dielectric multilayers with graded index treat the propagating waves impinging at
different angles very differently, due to total internal reflection. Such an ultra-sharp
change in the response can be exploited for filtering, manipulation and tailoring of spatially
distributed electromagnetic signals. Various utilities of the proposed filter such as power
splitting, DC isolation, beam shifting and low-profile energy interaction are demonstrated,
even in the presence of losses. The proposed setup can be vital as component in the
operation of integrated photonic devices dealing with optical signal processing and analog
information control
