Geometrical optics treatment of rectangular lightguides.
A geometrical optics theory is presented for the transmission of radiation in hollow overmoded rectangular lightguides with arbitrary wall materials, when the incident beam is injected into the waveguide by focusing to a waist in the guide entrance. Expressions are given for transmission coefficients, both of the total radiation and of that component of the surviving radiation which is plane polarized in a chosen direction.
