PHYSICAL SCIENCES INC. STTR Phase I Award, June 2023

Physical Sciences Inc. (PSI), in collaboration with Stanford University, will develop an electromagnetic simulation package used for the development and optimization of large-scale meta-optics, and demonstrate the functionality of the package in the long-wave infrared (LWIR). Our team will combine recent progress in physics-augmented deep learning neural networks with rigorous far-field diffraction integrals to assess the focusing efficiency of a 5cm x 5cm optic performing at a wavelength of 10 microns. Additionally, we will compare the performance of our modeling techniques to conventional central processing unit (CPU)-based Finite Difference Time Domain (FDTD) methods and show > 1000 x improvement in computational costs.
