Abstract

Magnetic lenses for surface magnetoplasmons (SMPs) in semiconductor-glass waveguide arrays (SGWAs) under Voigt configuration are proposed and investigated using simulations and theoretical analyses. The focusing and deflection functions of the magnetic lenses for normally incident SMP beams are demonstrated. For tilted SMP beams, the focal spot of the focusing lenses shifts laterally. Furthermore, it moves in the same direction in which the SMP beam is tilted. The focal length of the lenses is inversely related to the strength of the magnetic field. In this study, we provide a flexible method of steering the SMP beam in SGWAs at the THz region.
