Abstract
Photon sieve is a new nano-scale imaging aperture. When the diameter of pinholes of photon sieve is less than the wavelength of incident light, scaler diffraction theory is no longer valid for this condition. So vector theory must be used. The finite difference time domain (FDTD) is an effectual tool of numerical calculation and analysis of light field. We put forward researching high NA photon sieve with FDTD method. First we analyze the imaging properties of a single pinhole of photon sieve with vector diffraction theory and then introduce the principle and realization of FDTD. At last FDTD method is used to the numerical simulation of a pinhole. The simulation results are aslo compared to the results using scaler diffraction theory. It shows that scaler diffraction theory is not valid. The necessity and feasibility of using FDTD method to analyze and design high NA photon sieve is proved.
