Web∫ in the above equation simplifies to a voltage intensity integral, or VII. Thus, the final equation for PII can be written as PII VII cK = ρ 2 (2.15) 2.4 Radiation Force Lord Rayleigh laid the foundation for the theoretical description of radiation force in 1978, after it had first been observed by Dvo_ak in 1876 [Zieniuk and Chivers, 1976 ... WebThe Rayleigh-Sommerfeld diffraction (RSD) integral is used for the calculation of scalar wave propagation. In contrast to approximations such as Fresnel or Fraunhofer diffraction, the RSD gives an exact solution for the output field of a given input field [1-3].
