The optical transmission properties of metal-dielectric multilayer gratings have been investigated both experimentally and numerically. A remarkable transmission resonance, which makes a significant difference from that of traditional single/triple-layer analogs, has been reported. To understand its physical origin, a field-interference mechanism of dipole arrays induced by the lateral and vertical plasmon coupling has been suggested.

    The article offers a solution to the problem of poor resolution in terahertz imaging by using surface plasmon polaritons (SPPs) on corrugated wires to guide and superfocus terahertz radiation. An SPP is a coupled electromagnetic and electron-plasma polarization wave that can be excited at the...
