Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics
Advanced Optical Materials, Volume 13, Issue 32, November 14, 2025.8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Bistatic scattering from a cone frustum [PDF]
The bistatic scattering from a perfectly conducting cone frustum is investigated using the Geometrical Theory of Diffraction (GTD). The first-order GTD edge-diffraction solution has been extended by correcting for its failure in the specular region off ...

Automated composite ellipsoid modelling for high frequency GTD analysis [PDF]
The preliminary results of a scheme currently being developed to fit a composite ellipsoid to the fuselage of a helicopter in the vicinity of the antenna location are discussed under the assumption that the antenna is mounted on the fuselage.

A study of a collision avoidance system mounted on a curved ground plane [PDF]
Research conducted on a traffic advisory and collision avoidance system (TCAS 2) mounted on a curved ground plane is described. It is found that a curved finite ground plane can be used as a good simulation model for the fuselage of an aircraft but may ...

The Solving of Fermat’s Theorem [PDF]
, 2016 This article is dedicated to the proof of Fermat's theorem in general form. It is shown that besides the second degree equation, Fermat's equation does not contain any other integer solutions.
