On the regularization of Cauchy-type integral operators via the density interpolation method and applications
Vicente Gómez, Carlos Pérez-Arancibia
This paper presents a regularization technique for the high order efficient numerical evaluation of nearly singular, principal-value, and finite-part Cauchy-type integral operators…

Inverse design of large-area metasurfaces
Raphaël Pestourie, Carlos Pérez-Arancibia, Zin Lin +3
We present a computational framework for efficient optimization-based "inverse design" of large-area "metasurfaces" (subwavelength-patterned surfaces) for applications such as mult…

Sideways adiabaticity: Beyond ray optics for slowly varying metasurfaces
Carlos Pérez-Arancibia, Raphaël Pestourie, Steven G. Johnson
Optical metasurfaces (subwavelength-patterned surfaces typically described by variable effective surface impedances) are typically modeled by an approximation akin to ray optics: t…
