TOM 7 Thermal radiation and energy management

Casimir-Lifshitz force manipulation through materials optical properties

Sol Carretero Palacios1, Victoria Esteso2, Hernán Míguez2

1Universidad Autónoma de Madrid, Spain; 2Institute of Materials Science of Seville, Consejo Superior de Investigaciones Científicas (CSIC)- Universidad de Sevilla (US)

We present a theoretical study about the influence of the materials optical properties on the Casimir-Lifshitz force (F(C-L)) in the plane-parallel geometry. The use of multilayer structures (MLS) and optical resonators (OR) enables to tune the nature and intensity of F(C-L). Layering results in optical interference effects that modify the optical losses of the MLS, which, according to the fluctuation-dissipation theorem, affect F(C-L). High Q-factor OR based on levitation properties subjected to repulsive F(C-L) allow, an indirect accurate prediction of the equilibrium distance at which part of the OR levitates

TOM 7 Thermal radiation and energy management

Efficient computation of EM scattering from a dielectric cylinder covered with graphene strips for heat transfer

Youssef Jeyar1, Mauro Antezza1,2, Brahim Guizal1

1Laboratoire Charles Coulomb (L2C), UMR 5221 CNRS-Université de Montpellier, F-34095 Montpellier, France; 2Institut Universitaire de France, 1 rue Descartes, Paris Cedex 05 F-75231, France

We present a numerical approach for the solution of EM scattering from a dielectric cylinder partially covered with graphene. The result is a very simple and very efficient method allowing the study of diffraction from such structures. Our ultimate goal is to apply this approach to radiative heat transfer between graphene coated cylinders and planes.

TOM 7 Thermal radiation and energy management

Spectrally narrow near-field thermal emission of sapphire: a Casimir-Polder atomic sensor vs. emissivity spectrum

J.C. de Aquino Carvalho1, I. Maurin1, A. Laliotis1, D. de Sousa Meneses2, D. Bloch1

1Universite Sorbonne Nord, UMR 7538 du CNRS, Villetaneuse, France; 2CNRS UPR 3079, Orleans France

Near-field thermal exchanges are strongly enhanced by spectrally narrow surface mode emission. The resonances of sapphire surface emission are studied by two methods, up to 1000 K: (i) An atom-filtered information is provided through magnification of the Casimir-Polder dispersion force on Cs(7P), owing to a coincidence between the sapphire surface mode and atomic couplings; (ii) Fitting the broad spectrum of far-field thermal emission of sapphire allows to recover the permittivity, and then the surface response. Sapphire birefringence is shown to make the situation complex.
