Abstract

This study presents the first numerical solution to the 3D diffraction problem involving perfectly electric conducting (PEC) parallel circular double disks, excited by an arbitrarily polarized and located Hertzian dipole, using the Method of Auxiliary Sources (MAS). A comprehensive theoretical framework is established, and numerical simulations are conducted to analyze the frequency characteristics and field distributions of PEC double disks. The study investigates the effects of various parameters, such as disk radius, inter-disk distance, wavenumber, incident angle source location, and the dipole's position along the coordinate axes inside the disks, on the system's resonance behavior. The convergence of the MAS is thoroughly analyzed to ensure numerical reliability. These numerical results contribute valuable insights into the resonance characteristics of PEC double disks across various configurations. They serve as a guide for designing and optimizing resonators used in microwave and optical system applications.
