This project focuses on the dielectric sheet perturbation to the dominant TEl 11 mode resonant frequency of a circular cavity. The dielectric sheet of flat substrate materials is placed at the middle of the air-filled cavity, introduced discontinuities and disturbs the configuration of electromagnetic fields in the cavity.
