Modeling Several Optical Components Using Scalar Diffraction Theory [PDF]
Applied Sciences, 2022 Compound systems are generally treated by geometrical optics, for instance, through the Gauss’ formalism. The objective is to simplify the process of image formation. However, this formalism does not include the wave characteristics of light and boundary

Diffractive Refractometer Based on Scalar Theory [PDF]
Polymers, 2023 The measurement of the refractive index typically requires the use of optical ellipsometry which, although potentially very accurate, is extremely sensitive to the structural properties of the sample and its theoretical modeling, and typically requires specialized expertise to obtain reliable output data.

A 10× continuously zoomable metalens system with super-wide field of view and near-diffraction–limited resolution [PDF]
NanophotonicsMoiré metalens is attractive for imaging applications due to their compact form factor and high zoom ratio. Here, we propose a novel Moiré zoom metalens system that achieves a continuous 10× zoom over a focal length range of 2.2–22 mm at 1,064 nm, while ...

Photonic-Doppler-Velocimetry, Paraxial-Scalar Diffraction Theory and Simulation [PDF]
, 2015 In this report I describe current progress on a paraxial, scalar-field theory suitable for simulating what is measured in Photonic Doppler Velocimetry (PDV) experiments in three dimensions. I have introduced a number of approximations in this work in order to bring the total computation time for one experiment down to around 20 hours. My goals were: to
