PECULIARITIES IN THE DIELECTRIC RESPONSE OF NEGATIVE-PERMITTIVITY SCATTERERS

Backward Waves and Negative Refraction in Uniaxial Dielectrics with Negative Dielectric Permittivity along the Anisotropy Axis

Veselago medium (also called double negative material, backward medium, left-handed medium) is a medium with both negative isotropic dielectric permittivity and permeability. It has the effect of backward waves with negative (anomalous) refraction, in contrast to the usual forward waves with normal refraction in normal isotropic dielectrics and/or magnetics. In this paper, examples of the exist...

Dielectric Permittivity and Electric Modulus in Bi2Ti4O11

Thickness Dependent Dielectric Strength of a Low-permittivity Dielectric Film

The dielectric strength of a promising interlevel low relative permittivity dielectric is investigated for various film thicknesses and temperatures by using I-V measurements with metalinsulator-semiconductor (MIS) structures. It is found that the dielectric breakdown mechanism also depends on thickness. For relatively thick films (thickness >500 nm), the dielectric breakdown is electromechanic...

Wood’s anomalies for arrays of dielectric scatterers

The Rayleigh Wood anomalies refer to an unexpected repartition of the electromagnetic energy between the several interference orders of the light emerging from a grating. Since Hessel and Oliner (Appl. Opt. 4, 1275-1297 (1965)), several studies have been dedicated to this problem, focusing mainly on the case of metallic gratings. In this paper, we derive explicit expressions of the reflection c...
