Welcome to our group website!
The Applied Micro/Nano Electromagnetics Research Laboratory, hosted at the University of California, Davis and headed by Prof. J. Sebastian Gomez-Diaz, focuses on multidisciplinary areas of electromagnetic wave propagation and radiation from microwaves and terahertz frequencies to the infrared band, non-reciprocal and nonlinear phenomena, plasmonics, sensing, 2D and reconfigurable materials, as well as metamaterials/metasurfaces. In particular, our group is interested in the efficient control and manipulation of electromagnetic waves in unprecedented ways, aiming to overcome the limitations of current sensing technology and communication systems in terms of dynamic reconfiguration, integration and miniaturization while simultaneously boosting their performance and functionalities.
If you are interested in our research, please feel free to contact me.
We are actively searching for brilliant and motivated PhD students. Check Openings!
