Abstract :
Terahertz pulse generation from circular InAs apertures of sub-wavelength diameter is studied. Temporal advancement occurs for the pulses generated from sub-wavelength excitation InAs apertures. This behavior is explained by the dependency of excitation intensity and size, and can be applied to recognition of sub-wavelength-size patterns.
