DFlat is a forward and inverse design framework for flat optics. Although specially geared for the design of metasurface optics, it may be used for any end-to-end imaging and sensing task.

A Generic Framework for Optical Inverse Design

This repository hosts a simple demonstration of a deep learning approach for the inverse design of patch antennas. The goal is to explore energy-efficient designs and to significantly reduce simulation cost compared to conventional methods.

MATLAB implementation of the Huygens-Fresnel principle for the calculation of the scattering farfield pattern produced from the illumination of a finite-aperture rectangular metasurface.

Inverse design of Plasmonic Metasurfaces with Bidirectional Adversarial AutoEncoder

Providing work samples of electromagnetic, RF, antenna, and radar system analysis that I performed for graduate school assignments.

(Tensorflow Version) D-Flat is a forward and inverse design framework for flat optics. Although specially geared for the design of metasurface optics, it may be used for any end-to-end imaging and sensing task.

Meta_SCMT is a software to inverse design large-area dielectric metasurface. The key factor that differentiates the Meta_SCMT from current Local Periodic Approximation(LPA) based methods is that Meta_SCMT can achieve fullwave-level accuracy with much less computational resource.

code for Large area optimization of meta-lens via data-free machine learning

SmartGlass (SG) is a python implementation of a diffractive optical neural network. Currently, it supports training an all-optical classifier (e.g. classify hand-written digits MNIST dataset). Besides, the framework can also be used to design optics based on a task like focusing and beam steering. However, custom object functions should be defin…

MATLAB functions to plot 2D or 3D radiation & scattering patterns, intended for custom visualization of the response of antennas & metasurfaces.

The lib is used to study the ideal behavior of metasurface. For classic optics, there are good ray tracing python libraries that support classic optics, like RayTracing (https://github.com/DCC-Lab/RayTracing#raytracing) and rayoptics (https://ray-optics.readthedocs.io/en/latest/).
