Optimizing the Drude-Lorentz model for material permittivity: Examples for semiconductors [PDF]
, 2017 Approximating the frequency dispersion of the permittivity of materials with simple analytical functions is of fundamental importance for understanding and modeling their optical properties. Quite generally, the permittivity can be treated in the complex

Measurement of Complex Permittivity in Free Space
Procedia Engineering, 2015 AbstractThe paper describes the measurement of complex permittivity in free space. It is an advanced non-contact method which is used to find the electromagnetic properties of materials. In this case it involves the materials which are used in aviation technology, especially for hardening the avionics against electromagnetic interference. A specialized

Entanglement transformation at absorbing and amplifying four-port devices [PDF]
, 2000 Dielectric four-port devices play an important role in optical quantum information processing. Since for causality reasons the permittivity is a complex function of frequency, dielectrics are typical examples of noisy quantum channels, which cannot ...
