The heterodyne beat frequency method of determining dielectric constants has been applied to the measurement of the dielectric constant of air with an applied frequency of field of 900,000 cycles per second. Radio broadcast signals, stripped of modulation, were used as sources of alternating current...
IN recent years, a large number of experiments have been carried out on the dielectric constant of ionised air with the object of verifying the Eccles-Larmor theory, which demands that the dielectric constant of an ionised gas should be less than unity. Study of the literature on the subject...
Generally, the dielectric constant of air is defined as 1 and other dielectric constants are determined with reference to it. Other properties of interest in a dielectric are dielectric strength, a measure of the maximum voltage it can sustain without significant conduction, and the degree to ...
5. The dielectric constant between two metal lines will be affected by the insulator encasing the structure. For example, the effective intralevel dielectric constant for the metal lines shown in Fig. 4 will be higher than 1.06 (the dielectric constant of air), due to fringing of the ...

Low Dielectric Constant Materials for IC Intermetal Dielectric Applications: A Status Report on the Leading Candidates For over two years, intensive efforts at SEMATECH and elsewhere have focused on identifying low dielectric constant (low 蔚) materials which possess all of the required properties and ...
While for the realistic energy storage of capacitors, a bottle-neck challenge is how to maximally enhance the εr and simultaneously keep a high Eb (>400 MV/m)) [23,24]. Because the working electrical field (Eworking) of the capacitor is a constant high value [36], such as 200 MV/...
PURPOSE: To cope with the achievement of the high speed of a circuit by providing the constitution where a bonding agent is filled with minute air bubbles, and decreasing the electric constant of the bonding agent. ;CONSTITUTION: A conduting foil 2 is laminated and bonded on an insulating bas...
