| Popis: |
In this paper the effects of subwavelength antenna resonator element dimensions on the anomalous reflection properties of metasurfaces operating in the millimeter wave and terahertz frequency regions are investigated. Such two-dimensional structures are finding uses as flat optics in a variety of applications including beam steerers, reflectarrays, and broadband, polarization-independent radar absorbers. Numerical simulations were performed to characterize the reflection phase of square resonators of varying dimensions for several metasurface and reflectarray designs. A simple empirical model is developed for efficient characterization of metasurface phase characteristics in lieu of expensive numerical simulation software. |
