Resonance Properties of Optical All-Dielectric Metamaterials Using Two-Dimensional Multipole Expansion [PDF]

, 2012
We examine the electromagnetic response of metamaterial unit elements consisting of dielectric rods embedded in a non-magnetic background medium. We establish a theoretical framework where the response is described through the electric and magnetic ...

Measurement of relative permittivity of LTCC ceramic at different temperatures

AIP Advances, 2014
Devices based on LTCC (low-temperature co-fired ceramic) technology are more widely applied in high temperature environments, and the temperature-dependent properties of the LTCC material play an important role in measurements of the characteristics of ...

Modeling columnar thin films as platforms for surface-plasmonic-polaritonic optical sensing

, 2009
Via exploitation of surface plasmon polaritons (SPPs), columnar thin films (CTFs) are attractive potential platforms for optical sensing as their relative permittivity dyadic and porosity can be tailored to order. Nanoscale model parameters of a CTF were

Size-Dependent Bruggeman Approach for Dielectric-Magnetic Composite Materials

, 2004
Expressions arising from the Bruggeman approach for the homogenization of dielectric-magnetic composite materials, without ignoring the sizes of the spherical particles, are presented. These expressions exhibit the proper limit behavior.
