....slope diffraction. Slope diffraction is based not on the magnitude of the incident field at the point of diffraction, but rather on the slope magnitude of the incident field at the point of diffraction. The application of slope diffraction to cavity backed antennas is given in detail in reference[2]. In the present report, a combined FEM MoM method is used to analyze the elliptically polarized cavity backed antennas in a finite ground plane. GTD, with slope diffraction coefficients is used to augment the radiation patterns of these antennas on a finite ground plane. A particular case of a ....

The midpoints on the two edges of length W 2 are given by A and B, respectively, whereas the midpoints on the two edges of length W 1 are given by C and D, respectively. The total diffracted field at A and B are given by [2,6] (11) 12) for polarization, and (13) H qA d 1 2 H q ff d p 2 0 , D s r cA x , 1 y b o n , 1 jk o H q ff q d p 2 0 , D s y r cA x , 1 y b o n , ....
