Abstract

The analysis presented in the above titled paper is defective because equations (7a)-(7d) are based on the assumption that the complex impedances Z0 and ZL do not change when the frequency changes from f1 to f2 = mf1. As a result, the numerical solutions based on these equations are not valid either.
