Abstract

Tailoring the properties of an optical beam incident on a one dimensional metallic grating can attain a substantial control over the excited surface plasmon polariton wave. In this work we derive the complete analytical relations between the optical angles of incidence and the resulting surface plasmon propagation angle. These relations are demonstrated both numerically and experimentally. Following we show that there is an optimal grating that can excite any surface plasmon propagation angle between ±82.46 degrees and efficient polarization schemes which lead to negligible losses. Finally we introduce a formalism that relates general surface plasmon beams to corresponding incident optical beams and using it we demonstrate numerically a varying position surface plasmon hotspot generation.
