Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials, light propagation is unusual leading to novel ...

In their paper, the authors devised an elegant experiment to achieve repulsive Casimir forces by carefully selecting the dielectric permittivities of the involved materials." Inspired by this ...

The standard method to determine the suitable dispersion medium for carbon black particles is the measurement of its zeta potential in addition to its particle size in media of different relative ...
