The boundary residual method is a powerful technique for solving EM boundary-value problems. This technique produces matrices difficult to solve using many of the standard numerical techniques. This paper discusses lesser-known numerical aspects of this method, and it shows efficient and well-conditioned methods to solve both the homogeneous' and non-homogeneous boundary residual problem.

An inexpensive, easily fabricated, high quality, large aperture, pile-of-plates type, ir polarizer has been constructed having a polarization constant and insertion loss of 98% and 20%, respectively, using films of polyethylene kitchen wrap, each film being tuned for maximum performance at 10.6 microm by stretching.

Assuming no interference, recursion relations are derived, tabulated, and plotted, for the case where the number of plates is an integer power of two to form a set of graphs from which the transmission and reflection coefficients of a pile of identical, parallel, lossy plates can be obtained. Approximate closed form expressions, which are valid for any number of plates, are also derived and evaluated, giving an alternate analytical solution to the problem.
