Two additional xanthene analogues are termed fluorescent brighteneis. Fluorescent Brightener 74 (Cl 45550) and Fluorescent Brightener 155 (Cl 45555) are used in the formulation of solid dielectric compositions for application in high voltage cables to prevent conductive treeing. 

The field of transducer matrices for electrical properties covers many devices containing lanthanides. For example, capacitors are miniaturized and new dielectric compositions...

Figure 4 presents the variation of with p for different metal/dielectric composites, measured at different excitation wavelengths and with different pulsewidths, as selected from the literature [74, 139, 163, 180, 190-193]. The influence of both X and t on the nonlinear response will be discussed in Section 8. Nevertheless, one can already notice that the concentration dependence of ...

It has been observed in several studies that the use of organic monolayers or thin polymer phases to modify the surfaces of inorganic dielectric materials often improves the performance of these devices. This strategy has been employed for modification of Si02 [58] and AI2O3 surfaces [38] and more complicated dielectric composite materials.

On the other hand, nonferroelectric pyrochlores may serve as technologically useful dielectrics in other applications, such as temperature-stable dielectrics or microwave dielectrics. It is important to understand the structural relationship between the perovskite and pyrochlore phases in the Pb-based systems and to elucidate the thermodynamic and kinetic factors that may influence the phase equilibrium. Understanding these will allow a more systematic method of tailoring dielectric compositions to applications.

The other feature that emerges from the experimental data is the functional dependence of the observed o x) that is manifested in particular by the conductivity exponent t. Having the framework given in Sections 5.2-S.4, we can understand the various observed values of t as follows. In the cases where the onset of percolation is associated with the coalescence of particles (as in granular metals [42]) or coalescence-like (as in semiconductor-dielectric composites [41] shown in Figure 5.6), the values of t [35, 39, 40, 42, 59] are, within the experimental uncertainty, very close to the classical critical values of 1.7 < t < 2 that were derived from calculations or computations [1, 3, 15]. This observation is well understood by following two considerations. Either, as suggested above, we approach the S Z picture, or we can virtually divide the continuous phase network into small elements (say, spheres or... 

Dielectric compositions for insulator fabrication include insulator dielectrics or glass filled with ceramic dielectrics (alumina and silica added to the glass), ceramic-filled glasses (glass and refractory oxides), and crystallizing dielectrics (crystallizable glass and crystallization agents). 

In addition to the conductors, compatible crossover dielectric, resistor series, and brazing materials are available. The dielectric composition matches the TCE of AIN substrates, and resistance values of resistors range from 100 mQto 1 KQ/sq. Typical properties of the resistors include TCR... 

A colorant may be added to the dielectric composition. This yields a paste that is much easier to process (i.e., coat, expose, develop, and fire) than a clear paste. Many inorganic pigments may be employed for this purpose. 

Structurally, metamaterials are usually metal-dielectric composites ordered in ID, 2D, or 3D arrays, where a certain metallic pattern (denoted as electromagnetic...
