Determination of Effective Permittivity and Permeability of Metamaterials from Reflection and Transmission Coefficients [PDF]
, 2002 We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lenghts of electromagnetic metamaterials, to determine the effective permittivity and permeability.

Abnormal enhancement of electric field inside a thin permittivity-near-zero object in free space [PDF]
Phys. Rev. B 82, 075118 (2010), 2010 It is found that the electric field can be enhanced strongly inside a permittivity-near-zero object in free space, when the transverse cross section of the object is small and the length along the propagation direction of the incident wave is large ...

Conductivity and permittivity of dispersed systems with penetrable particle-host interphase [PDF]
Condens. Matter Phys., 2013, vol. 16, No. 1, 13401:1-10, 2013 A model for the study of the effective quasistatic conductivity and permittivity of dispersed systems with particle-host interphase, within which many-particle polarization and correlation contributions are effectively incorporated, is presented.

Permittivity-Asymmetric Quasi-Bound States in the Continuum. [PDF]
Nano letters (Print), 2022 Breaking the in-plane geometric symmetry of dielectric metasurfaces allows us to access a set of electromagnetic states termed symmetry-protected quasi-bound states in the continuum (qBICs).

Composite medium with simultaneously negative permeability and permittivity
Physical Review Letters, 2000 We demonstrate a composite medium, based on a periodic array of interspaced conducting nonmagnetic split ring resonators and continuous wires, that exhibits a frequency region in the microwave regime with simultaneously negative values of effective ...

On the permittivity of titanium dioxide
Scientific Reports, 2021 Conductive rutile TiO2 has received considerable attention recently due to multiple applications. However, the permittivity in conductive, reduced or doped TiO2 appears to cause controversy with reported values in the range 100–10,000.

PERMITTIVITY MEASUREMENTS OF BIOLOGICAL SAMPLES BY AN OPEN-ENDED COAXIAL LINE [PDF]
, 2020 We previously reported on the complex permittivity and dc conductivity of waste-activated sludge. The measurements, spanning a frequency range of 3MHz to 40GHz, were made using an open-ended coaxial transmission line.
