Dear Steven and meep users, I have modeled a simple cylindrical RF cavity resonator. Dimensions are Length 0.1223642686 meters, Dia = 0.0754898000 meters using perfect metal, and a characteristic length, a = 0.01. The TE 1,1,1 mode resonant frequency analytical solution for this cavity is 2.45 GHz. Excited using Ez and in cylindrical coordinates, Meep/Harminv calculates resonant frequency as 1.87 GHz. WHY?
My lattice is large enough, my pml layer is large enough (Both are more than double the minimum) and I get the same answer from meep for resolutions ranging from 4 up to 720. I have systematically calculated analytical solutions for cavity resonance up to TE 5,5 and TM 5,5, 60 frequency calculations. There are no analytical solutions for resonance of this cavity below 2.45 GHz either TE or TM mode. Where should I look next for resonance at 2.45 GHz from meep?
