Abstract
Unidirectional transmission of electromagnetic
waves has attracted great interest due to its wide modern
optical applications. This study theoretically demonstrates
a one-way transmissive optical device with a high-contrast
forward-to-backward ratio at the near-infrared region. The
polarization-independent optical diode-like mechanism is
designed using a metasurface diffraction grating configuration
with symmetry breaking property along the wave propagation
in which the working principle is based on the excitation
of surface plasmon modes at the interfaces of thin metallic
interlayer and their coupling to the radiation modes.
