ZURITA-SANCHEZ, Jorge R.. Quasi-static electromagnetic fields created by an electric dipole in the vicinity of a dielectric sphere: method of images. Rev. mex. fis. [online]. 2009, vol.55, n.6, pp.443-449. ISSN 0035-001X.

We present a quasi-static description of the electromagnetic fields created by an oscillating electric dipole in the vicinity of a dielectric sphere. In this description: the fields are generated by image sources, a simple physical picture of the electromagnetic response of the dipole nearby a dielectric sphere is obtained, and the nearfields are calculated from the Green tensor of a bulk medium. This quasi-static description can be applied to study radiative properties of emitters (molecules, atoms, etc.) placed in the vicinity of a dielectric spherical nanoparticle.

Palavras-chave : Electric dipole radiation; dielectric sphere.
