Dr. Denison et Rw. Scharstein, DECOMPOSITION OF THE SCATTERING BY A FINITE LINEAR-ARRAY INTO PERIODIC AND EDGE COMPONENTS, Microwave and optical technology letters, 9(6), 1995, pp. 338-343
The field scattered by each element in a finite array is decomposed in
to the contribution of the infinite or periodic array, a component due
to the presence of the left edge of the away, and a component due to
the right edge of the array. The scattered field due to either away ed
ge is derived from a separate analysis of the appropriate semiinfinite
army and is interpreted in terms of a decaying wave that is launched
from the away end. (C) 1995 John Wiley and Sons, Inc.
