Applications of Effective Medium Theories in the Terahertz Regime
Year: 2010
Type: book-chapter
Abstract: In this chapter a short introduction into a selection of quasi static effective medium theories was presented. Their potential and restrictions were illuminated by a choice of representative application scenarios ranging from polymeric compounds to biological samples. However, the relatively long wavelengths of the terahertz waves enables for a wide applicability within this frequency range without the necessity of including volumetric scattering effects in the calculations. Therefore, an accurate analytical modelling of various problems can be achieved utilizing such EMTs. The Table 2 gives a short overview of exemplary application scenarios and the EMTs of choice. Application Scenario Mixtures with high contrast in permittivity, spherical particles Mixtures with high contrast in permittivity, ellipsoidal particles Mixtures with low contrast in permittivity, irregular or unknown shaped particles Mixtures of powders, porous pellets Mixtures consisting of isotropic components EMT of choice EB EB, PvS LLL, CRI LLL, CRI EB, PvS
