Phonon-polariton meta-atoms for far infrared range

Polarizabilities of spherical subwavelength silica glass particles are investigated having regard to material dispersion. It is shown that the ranges of the negative electric and magnetic polarizabilities almost coincide. This allows the particles in question to be used for producing media with a ne...

Description
Summary:Polarizabilities of spherical subwavelength silica glass particles are investigated having regard to material dispersion. It is shown that the ranges of the negative electric and magnetic polarizabilities almost coincide. This allows the particles in question to be used for producing media with a negative refractive index.
