Professor Ergun Simsek's research interest is focused on the electromagnetic and optical phenomena associated with multilayered structures and nanoscale materials. He is interested in near-field, light-matter interactions, including plasmonic and non-linear effects, and their applications. He is the director of GW WavesLab, where Dr. Simsek and his students conduct advanced experimental and numerical studies on plasmonic devices, 2D layered materials including graphene, and nano structures fabricated with laser ablation.

Current Research

Professor Ergun Simsek's research interest is focused on the electromagnetic and optical phenomena associated with multilayered structures and nanoscale materials. Even though his work covers a broad range of applications, the center point of his research is "multilayered media." Both experimentally and numerically, his research group is trying to understand how electromagnetic waves (including light) propagates, gets absorbed in and scattered from arbitrary targets embedded in stratified media. Some of his recent studies include 2D material synthesize, ultra-broadband highly efficient absorber design, tunable surface plasmon resonance sensor design and characterization, and laser ablation.
