Abstract: Abstract Some formulas are developed to simplify the calculations of the vectorial Rayleigh–Sommerfeld (R–S) diffraction integrals when several types of polarized fields are used as illuminating light. It is proved that when rotationally symmetric functions… read more here.

Abstract: In this paper, different diffraction theories for estimating the diffraction field patterns modulated by metasurfaces are firstly revisited. Further reformulation of these theories is performed to better reveal their inherent mechanisms and differences. To compute… read more here.
