Identifier: http://hdl.handle.net/1959.14/309826
Description: We present a study of the properties of the transversal "spin angular momentum" and "orbital angular momentum" operators. We show that the "spin angular momentum" operators are generators of spatial t... More

Identifier: http://hdl.handle.net/1959.14/281080
Description: We will show how to extract information from the Mie coefficients to properly design dual systems combined with chiral elements for having optically active structures. Such optically active elements w... More

Identifier: http://hdl.handle.net/1959.14/263236
Description: We present how the angular momentum of light can play an important role to induce a dual or anti-dual behaviour on a dielectric particle. Although the material the particle is made of is not dual, i.e... More

Identifier: http://hdl.handle.net/1959.14/263708
Description: In this Letter, we show that the electromagnetic duality symmetry, broken in the microscopic Maxwell's equations by the presence of charges, can be restored for the macroscopic Maxwell's equations. Th... More

Identifier: http://hdl.handle.net/1959.14/277869
Description: We show the relation between optical activity and helicity for the scattering of chiral particles. The results show how to design chiral structures for an omnidirectional optically active response ind... More

Identifier: http://hdl.handle.net/1959.14/276958
Description: We present a method to enhance the ripple structure of the scattered electromagnetic field in the visible range through the use of Laguerre-Gaussian beams. The position of these enhanced ripples as we... More

Identifier: http://hdl.handle.net/1959.14/198341
Description: We present a new method to address multipolar resonances and to control the scattered field of a spherical scatterer. This method is based on the engineering of the multipolar content of the incident ... More

Identifier: http://hdl.handle.net/1959.14/199598
Description: We propose a theoretical and practical framework for the study of light-matter interactions and the angular momentum of light. Our proposal is based on helicity, total angular momentum, and the use of... More

Identifier: http://hdl.handle.net/1959.14/199543
Description: The scattering of circularly polarised Gaussian beams impinging on a cylindrical nanohole in a metallic thin film contains phase singularities. These experimental observations are due to changes in th... More

Identifier: http://hdl.handle.net/1959.14/194805
Description: Multipolar solutions of Maxwells equations are used in many practical applications and are essential for the understanding of light-matter interactions at the fundamental level. Unlike the set of plan... More
