This note represents an attempt to come to grips with the general problem of radiation transmission and backscatter from one- and two-layer slabs of finite thickness. The case where the second of two layers is of infinite thickness is treated as a special case. The method is capable of being generalized still farther to treat multi-layer finite slab problems. In the study of radiation reflection, extensive effort has been devoted to the case of the semi-infinite homogeneous slab. However, information on slabs of finite thickness and on multilayered slabs is required for the study of many practical applications of radiation reflection. In this note, the study of radiation reflection from a two-layer slab is based on existing theory for finite and infinite slabs. A two-layer slab implies that the slab consists of two layers which in essence are homogeneous but neither of the two layers is necessarily infinitely thick. Before discussing the two-layer problem, a brief description is first given of finite single-layer slabs. Then, the two-layer problem will be treated mathematically as an extension of the single-layer slab problem. In this note, only theoretical aspects of the subject are presented. In a following report, the technical aspects of solving equations derived in this note will be discussed.
