Negative scattering asymmetry parameter for dipolar particles: Unusual reduction of the transport mean free path and radiation pressure
R. Gomez-Medina, L. Froufe-Perez, M. Yepez +3
We establish a relationship between the electric magnetic dipole interaction force from a plane wave on a small magnetodielectric particle, the transport cross-section and the scat…
Angle-Suppressed Scattering and Optical Forces on Submicron Dielectric Particles
M. Nieto-Vesperinas, R. Gomez-Medina, J. J. Saenz
We show that submicron Silicon spheres, whose polarizabilities are completely given by their two first Mie coefficients, are an excellent laboratory to test effects of both angle-s…
Strong magnetic response of submicron Silicon particles in the infrared
A. Garcia-Etxarri, R. Gomez-Medina, L. S. Froufe-Perez +6
High-permittivity dielectric particles with resonant magnetic properties are being explored as constitutive elements of new metamaterials and devices in the microwave regime. Magne…
Full transmission through perfect-conductor subwavelength hole arrays
F. J. Garcia de Abajo, R. Gomez-Medina, J. J. Saenz
Light transmission through 2D subwavelength hole arrays in perfect-conductor films is shown to be complete (100%) at some resonant wavelengths even for arbitrarily narrow holes. Co…
Controlling absorption resonances from sub-wavelength cylinder arrays
Marine Laroche, Raquel Gomez-Medina, Juan Jose Saenz
The absorption and extinction spectra of sub-wavelength cylinder arrays are shown to present two different kind of resonances. Close to the Rayleigh anomalies, the diffractive coup…
Resonant radiation pressure on neutral particles in a waveguide
R. Gomez-Medina, P. San Jose, A. Garcia-Martin +3
A theoretical analysis of electromagnetic forces on neutral particles in an hollow waveguide is presented. We show that the effective scattering cross section of a very small (Rayl…
