Name-value arguments must appear after other arguments, but the order of the pairs does not matter. Example: Name="Air" Name— Name of dielectric material string (default) | cell array Name of the dielectric material, specified as a string for single material or a cell array of strings ...
The value of the dielectric constant represents the ratio of thecapacitanceof the capacitor whose test material is the dielectric to the capacitance of a capacitor whose dielectric is vacuum (or air). It is mathematically expressed as the following: k = ϵ/ϵ0 The variables in this equation...
In understanding the nature of the density dependence of the dielectric properties of particulate materials, relationships between the dielectric properties of solid materials and those of air–particle mixtures, such as granular or pulverised samples of such solids, are useful. In some instances, ...
Classically, dielectric materials may include the use of ceramic, glass, plastics, mica, and metal oxides, even though sometimes distilled water, dry air, and vacuum may be considered as exceptional and excellent tin dielectric materials. Kannan et al. (2005) stated that dielectric material is ...
We theoretically and experimentally demonstrate that also in the inverted case of an air void inside a homogenous high-index medium, localized optical modes emerge, which are confined within the nanoscale low-index void by virtue of the finite reflectance at the material discontinuity. While the ...
In the HCC design, the traditional dielectric insulating layer is replaced by air... C Zhu,Y Zhuang,Y Chen,... - 《Review of Scientific Instruments》 被引量: 0发表: 2018年 The modified quarter-wavelength resonator method for parameters control of the coaxial connector dielectric beads The ...
polarizabilities as determined from the Clausius-Mosotti equation and those calculated from the sum of oxide polarizabilities according to α D (mineral) = Σα D (oxides) for this group of spinels ranges from + 1.1 to + 3.2%, well above the agreement value of 0.5–1.0% found for well-...
This type of waveguides is based on a single or dual metal wires and ribbons, or arrays of metal wires and ribbons suspended in air [194–196]. Thanks to the guidance in air, these waveguides provide both low dispersion and propagation loss in a wide spectral range. At the same time, ...
4(a, b). Additionally, the filling of air results in high porosity and considerably enhances the cement matrix's impedance matching efficiency, as illustrated by the loss mechanism in Fig. 4(c). The findings showed that the foamed cement-based composites with mixed dielectric fibers, including...
(aramid) 3.8-4.1 Aromatic amines (woven) 3.8-4.1 Ceramic filled PTFE 6.0-10.2 Foamclad (Arlon patent) 1.15-1.3 Water 70 It can be seen that the ideal material for high speed and high frequency applications is the air medium wrapped by copper foil, and the thickness tolerance is in + /...
