PIC Simulation of Periodic Dielectric Cerenkov Maser

According to the analysis of periodic dielectric Cerenkov maser, by using of equivalence theory, periodic dielectric cerenkov maser is considered as uniform anisotropic dielectric. the dispersion equation of periodic dielectric cerenkov maser are derived. Through the way of particle-in-cell (PIC) simulation, we can see that the output power and output frequency will be changed corresponding to the εz and εr (same as to adjust the percentage of dielectric area). So it is possible to achieve high frequency microwave output by adjusting the width of dielectric film.
