摘要Influence of hyperlens structure parameters, such as curvature radius and layer number, and incident wavelength on the beam propagation is numerically investigated by FDTD. It is found that the intensity and the full width at half maximum (FWHM) of the output beam can be controlled by the structure parameters and operating wavelength. The optimized structure parameters and operating wavelength are obtained, which will be of great significance in design and fabrication of optical hyperlens with high resolution.
