چکیده
|
the funneling profile of enhanced light transmission through a subwavelength slit in a perfect electric conductor is studied with finite-difference time-domain simulation. from the wave-charge interaction dynamics, it is found that the em wave energy is funneled while charges are accumulated at the edges of the slit. the poynting vector indicates a boundary within which the wave energy flows toward the slit. therefore, a funneling profile is defined by this boundary; as the slit width and thickness determine the transmitted energy density, the size of the funneling area is a relevant quantity of major concern.
