title = "Simulating the response of nanostructures under a focused beam",
abstract = "Focusing the light onto nanostructures thanks to spherical lenses is a first step to enhance the field, and is widely used in applications needing strong light matter interactions. Nonetheless, the electromagnetic response of such nanostructures, which have subwavelength patterns, to a focused beam can not be described by classical optics. Here, we describe a formalism to efficiently compute the behavior of nanostructures under a focused beam based on an apodized decomposition on plane waves. Besides, each computation of a plane wave is done on only one period thanks to a conical B-spline modal method. Various examples illustrating the focusing are detailed, and in particular the possibility to move the focal spot and to tilt the focus beam.",
