3D metagrating testbed

stevengj commented 2 years ago

@jiaqi-jiang, I wanted to check on this sentence:

Efficiency: Deflection efficiency is defined as the intensity of light deflected to the desired diffraction order, normalized to the light intensity incident from within a semi-infinite silica substrate.

Is this equivalent to the total power (per unit cell) in the diffracted order, i.e. the Poynting flux, divided by the incident power (per unit cell)?

Also, you were going to clarify on using the harmonic mean?

jiaqi-jiang commented 2 years ago

Yes, that’s right.

I’ve updated README.md file. The FOM is defined in the paragraph after the schematic figure.

FOM = (1/eff_TE + 1/eff_TM)^(-1).
