Strong Resonance and Terahertz Wave Transmission Enhancement of Low-Porosity Metal Hole Array with Bow-Tie-Shaped Apertures

Nanocrystalline λ-Ti3O5was fabricated by carbothermal reduction of nano-TiO2. It exhibits a continuous and slow phase transition across a wide range of temperatures, which can lead to dynamic tuning of THz transmission.

Transmission Enhancement

Numerical simulation about transmission enhancement phenomenon on metal film hole array has been finished in the paper by East FDTD commercial software. In some wavelengths, relative transmission rate is more than 1 and we also study that the thickness of metal plate, the size of the hole and period on influence of the transmission rate. Transmission enhancement peak lowers with the increasing of silver film thickness, enlarger along with the increasing of the aperture, And when period of hole gets larger, transmission peak will shift.

Terahertz waves can pass through silicon wafer with less loss than traditional lenses. By selecting square, circular and sectors as building blocks, a serial of equivalent lenses for terahertz wave transmission were designed in the vertical plane of the silicon wafer, including hemispherical convex, concave mirror, triangular prism and spherocylinder lenses. The lens’ 2-D design in this work is much simpler than its actual 3-D shape. Besides high transmit ability, silicon wafer also has high refractive index. When a lens is oriented horizontally, it can act as a graded-index photonic crystal waveguide, due to the existence of a band gap, especially for cylinder and prism lens.
