Nowadays, there are several approaches that are considered to be promising for the further integration of photonic devices, including photonic crystal waveguides and devices, dielectric devices with high refractive index contrast, and surface plasmon waveguides and devices. Among them, researchers have designed a variety of surface plasmon waveguides and(More)
Terahertz (THz) imaging has become a hot research topic because of its wide applications ranging from biomedical science to astronomy. However, its resolution is also limited by the diffraction limit. Surface plasmonic resonance is a well-known technology that can manipulate the electromagnetic wave in the sub-wavelength region. This paper proposes a method(More)
