Diffraction is a classic optical phenomenon accounting for the light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

Linear transforms — like a Fourier transform — are a key math tool in engineering and science. A team from UCLA recently published a paper describing how they used deep learning techniques to design ...

Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...
