H2=H.H2;

numerator = integrate(H2,2:3,Hy,Hz)^2;

denominator = integrate(H2^2,2:3,Hy,Hz);

modal_area = numerator/denominator;

modal_area = modal_area*1e12; # convert from units of m^2 to um^2

f=getdata("frequencysweep","f_D");

plot(c/f*1e6,modal_area,"Wavelength (um)", "Effective Mode Area");

Hi, "E/H" field is only for modes at the given frequency, and the frequency-sweep does not give this output. Please check all the outputs :

If you want to get the "Effective Mode Area" at each frequency, you will need to write your own loop to sweep frequency, get H fields from the given mode, and then calculate the "Effective Mode Area".

Please note that you will need to have the "test_mode" in the global deck in order to complete the bestoverlap.
