08 03 2019The value of ε m is obtained by Maxwell–Garnett equation: ε m − ε 1 ε m + 2 ε 1 = ν 2 ε 2 − ε 1 ε 2 + 2 ε 1 (7) where ε 1 and ε 2 are the permittivity of the LTCC substrate and fluid filled in the microchannel respectively v 2 is the volume fraction of the fluid phase in two-phase mixed media which was ~50% for the developed sensor According to Equation (4) the

not forget about the principle of optical equivalence introduced by George Gabriel Stokes 150 years ago: It is impossible to distinguish two beams which are the sum of non-coherent simple waves if they have the same Stokes parameters So a judicious restriction on the detailed elaboration of diﬀerent com-ponents in dust modeling should be found IN THE KITCHEN 3 2

In the Maxwell Garnett and the Bruggeman formalisms the spatial distributions of the constituent materials are characterized simply by their volume fractions The strong-property-fluctuation theory (SPFT) which was originally developed to investigate wave propagation in continuous random mediums [ 32 33 ] provides a more sophisticated approach to homogenization

Based upon our compact group approach and the Hashin-Shtrikman variational theorem we propose a new solution which effectively incorporates many-particle effects in concentrated systems to the problem of the effective quasistatic permittivity of dispersions of graded dielectric particles After the theory is shown to recover existing analytical results and simulation data for

Also the Maxwell-Garnett model is found to clearly underestimate the overall results as illustrated in Fig 15 where numerically derived permittivity is plotted as a function of the Maxwell-Garnett prediction and compared to a y = x equation
