Abstract
A waveguide for submillimeter and infrared wavelength range electromagnetic radiation comprises a metal grating with a grating constant criterion: ##EQU1## BEING GREATER THAN (2/.lambda.).sup.2, WHERE .lambda. IS WAVELENGTH OF AN ELECTROMAGNETIC WAVE PROPAGATING FREELY IN THE SURROUNDING MEDIUM AND G.sub.X, G.sub.Y ARE GRATING CONSTANTS IN ORTHOGONAL DIRECTIONS. The constants g.sub.x, g.sub.y may be equal to each other or different.
