We report some of our recent progress in enhancing the extraordinary optical transmission (EOT), perfect absorption and field squeezing. Based on the excitation of surface plasmon waves in optical nano‐antennas, the extraordinary transmission of light through a vertical nano‐slit in a metal film is realized. Omni‐directional, broadband and polarization‐insensitive absorption of light is achieved in a thin metamaterial absorber which consists of cross‐antennas and a metal ground. A dielectric split ring inside a permeability‐near‐zero metamaterial is used to squeeze electromagnetic energy and obtain strong magnetic field at the gap without using any resonance mechanism.
