摘要：
Resonance and non-resonance types of total absorption of light by metallic gratings are discussed in connection with the energy flow distribution. Above the grooves the energy flow distribution for shallow and deep gratings is very similar, while in the grooves curls of flow exist. The resonance type of total absorption is accompanied by a strong compression of flow lines resulting in large electromagnetic enhancement, while for the non-resonance type the flow density near the grooves is not enlarged. © 1990.
