Abstract
A flexible hollow rectangular wave guide for transmission of radiation in the infrared portion of the spectrum, including infrared laser radiation. A wave guide which may be bent and twisted while providing low loss transmission of infrared radiation. An all metal wave guide with the width to heighth ratio at least 4 to 1. A wave guide with metal surfaces on the long dimension and dielectric surfaces on the short dimension and having a width to height ratio at least 2 to 1.

A hollow rectangular wave guide for transmission of radiation in the infrared portion of the spectrum, comprising:
- top and bottom walls of thin flexible material with metal inner surfaces spaced apart a distance a;
- and
- side walls of a flexible material and spaced apart a distance b, with the ratio of b/a at least about 4/1 and with each of a and b at least about ten times the wavelength of the infrared radiation.
