Thoughts on electromagnetics, antennas, metasurfaces, research, teaching and academic life.
01
Metasurfaces are artificially engineered two-dimensional structures composed of subwavelength elements arranged to manipulate electromagnetic waves in ways that are difficult to achieve with conventional materials. By carefully tailoring the geometry, orientation, and…
