Periodic structure ray method for analysis of coupling coefficients in large concave arrays. II. Application

For pt.I see ibid., vol.37, no.11, p.1377 (1989). The periodic structure ray method (PSRM) for evaluation of coupling coefficients in large concave array was developed in part I. The PSRM is illustrated here by an example of a circular cylindrical concave array of rectangular waveguide elements for which a modal solution also exists. Excellent agreement in amplitude and phase between the modal and the ray solutions is found. The results show that the PSRM is efficient and converges rapidly
