Concentric Layered Hermite Scatterers

A paper co-authored by Professor Kevin Parker and Dr. Jeffrey Astheimer of HABICO, Inc. titled "Concentric layered Hermite scatterers" will appear in the May 2018 issue of Physics Letters A and can be found here. The article demonstrates that the necessary and sufficient conditions for supra-Rayleigh scattering power laws - in the case where the inhomogeneous material property conforms to a piecewise continuous constant function - can be stated simply by considering moments of the inhomogeneous function and its spatial transform. This development opens an additional path for construction and use of scatterers with unique power law behavior.
