Faculty of Engineering, Carleton University, Ottawa l, Ontario. Received 30 November 1970. This letter suggests the following simplifications to the lengthy

Eqs. (3), (4), (7), and (8) of the paper by Dignam and Moskovits-that appeared recently in Applied Optics:1

678 APPLIED OPTICS / Vol. 10, No. 3 / March 1971

These simplifications follow from the trigonometrical relations:

The writer believes that this simplification will be helpful to the readers of Applied Optics.
