Dielectric microstrip line (DML) — A new transmission line for terahertz applications

This paper presents a multilayer dielectric transmission line - the dielectric microstrip line (DML), for the terahertz (THz) applications. This DML is a metal free transmission line eliminating metal loss, which can be a very serious problem at THz. The E

mode is the main mode in the DML for the electromagnetic wave propagation. A DML with standard waveguide operating within 0.220THz-0.325THz is designed, fabricated and measured for demonstration. With TRL calibration method, phase constant and attenuation constant of the DML are obtained.
