//For a circular resonator
D=12.5;//diameter in cm
l=5;//length of circular waveguide in cm
disp('Given the mode of operator is TM012 so here n=0,m=1,p=2');

//CALCULATION
a=D/2;//radius in cm
f0=((c/(2*(%pi)))*sqrt((Pnm/a)^2+((p*(%pi))/l)^2))/10^9;//The resonant frequency of a circular resonator in GHz
//OUTPUT
