F. Obelleiro et al., A PROGRESSIVE PHYSICAL OPTICS (PPO) METHOD FOR COMPUTING THE ELECTROMAGNETIC SCATTERING OF LARGE OPEN-ENDED CAVITIES, Microwave and optical technology letters, 14(3), 1997, pp. 166-169
The analysis of high-frequency scattering from electrically large open
-ended cavities ir addressed in this work. The magnetic field integral
equation (MFIE) is obtained for the equivalent currents an the interi
or cavity walls and is solved in a single iteration by using a new pro
gressive physical optics (PPO) algorithm. Numerical results that demon
strate the efficiency and accuracy of the proposed solution are presen
