ABSTRACT:
Preferred reflective surface wave processors employ cooperating serially disposed reflector sections. At least one reflecting section comprises an array of non-segmented reflecting grooves in which certain grooves are omitted to form a withdrawal array. Cooperatively coupled to this non-segmented array is an array of segmented grooves. The elements of the segmented array may be made up of progressively fewer segments in regularly spaced lines. The segments in any one segmented line may selectively be of equal lengths randomly spaced within a given line.
