Asymptotic expansions for the transmission eigenvalues of periodic scatterers of bounded support
Fioralba Cakoni, Shari Moskow
We consider the transmission eigenvalues for a bounded scatterer with a periodically varying index of refraction, and derive the first order corrections to the limiting transmissio…
Target Signatures for Anisotropic Screens in Electromagnetic Scattering
Fioralba Cakoni, Peter Monk
Anisotropic thin sheets of materials possess intriguing properties because of their ability to modify the phase, amplitude and polarization of incident waves. Such sheets are usual…
On the lack of external response of a nonlinear medium in the second-harmonic generation process
Fioralba Cakoni, Narek Hovsepyan, Matti Lassas +1
This paper concerns the scattering problem for a nonlinear medium of compact support, , with second-harmonic generation. Such a medium, when probed with monochromatic light beam…
Far field broadband approximate cloaking for the Helmholtz equation with a Drude-Lorentz refractive index
Fioralba Cakoni, Narek Hovsepyan, Michael Vogelius
This paper concerns the analysis of a passive, broadband approximate cloaking scheme for the Helmholtz equation in for or . Using ideas from transformati…
A Spectral Target Signature for Thin Surfaces with Higher Order Jump Conditions
Fioralba Cakoni, Heejin Lee, Peter Monk +1
In this paper we consider the inverse problem of determining structural properties of a thin anisotropic and dissipative inhomogeneity in , from scattering d…
