Differernt papers show the use of different materials for simulations to obtain zero index metamaterial, is there some kind of a guide in choosing the dielectrics and metals?
Yes...
Hi, i am modeling my unit cell structure (plasmonic rectangular slit) in COMSOL with silver metal as top layer and ITO as substrate. My transmittance, |S21|^2 is too small , ~ 6%. I have...
