Extended GSTCs and Multipolar Modeling of Spatially Dispersive Metasurfaces

2025

Abstract

Metasurfaces are 2D arrays of resonating particles whose microscopic properties can be tailored to produce a desired macroscopic field scattering response. A particularly interesting class of metasurfaces is nonlocal or spatially dispersive (SD) metasurfaces. For these surfaces, the induced currents on the surface are related to fields over an extended region of the structure. This nonlocality allows for the control of the angular scattering of the metasurface. The potential to tightly control the angular scattering response of a surface has led to SD metasurfaces finding potential applications in wave-based computing and space compression.

Mie scattering

The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere. The solution takes the form of an infinite series of spherical multipole partial waves. It is named after Gustav Mie. The term Mie solution is also used for solutions of Maxwell's equations for scattering by stratified spheres or by infinite cylinders, or other geometries where one can write separate equations for the radial and angular dependence of solutions.

Metamaterial

A metamaterial (from the Greek word μετά meta, meaning "beyond" or "after", and the Latin word materia, meaning "matter" or "material") is any material engineered to have a property that is rarely observed in naturally occurring materials. They are made from assemblies of multiple elements fashioned from composite materials such as metals and plastics. These materials are usually arranged in repeating patterns, at scales that are smaller than the wavelengths of the phenomena they influence.

Data compression

In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information.
