Broadband asymmetric transmission (AT) of linearly polarized light is an important but challenging functionality to realize. Leveraging a combination of a genetic algorithm optimization method and the membrane projection lithography fabrication approach, a three-dimensional metamaterial is demonstrated for broadband AT of linearly polarized mid-infrared light.

With modern nanofabrication technology, superfine features — or small structures inside metasurface components — can be made consistently, but this can affect the processing time. The goal of this research was to identify a method that would allow design of structures that can tolerate those inevitable defects and still perform well

Our new article on the explosion of Artificial Intelligence in Antennas and Propagation has been published in the June 2021 special issue of the IEEE Antennas and Propagation Society Magazine. focusing on Artificial Intelligence in Electromagnetics. The editors summarize our article thusly: “…Campbell et al. provide an overview of the state of the art (SoA) of the use of deep learning (DL) methods in problems of interest to the AP community, including forward modeling, inverse scattering and remote sensing, and inverse design (optimization). They also envisage DL’s potential impact on the IEEE Antennas and Propagation Society and discuss the application of new hardware advancements for computational electromagnetic simulations. They report several useful references to assist beginners in getting started with using DL in their own research.”
