Abstract
Coherent Perfect Absorption is one form of reflectionless scattering, involving transduction of an adapted input field. We present a general theory of reflectionless scattering, which includes CPA, based on choosing a subset of input channels and requiring no backscattering into them. We show that infinitely many such solutions exist at complex frequency, can be calculated efficiently, and can be made accessible via tuning a single structural parameter. Optimization of a parameterized structure can achieve high quality signal routing.
