relative dielectric constant การใช้

• Relative dielectric constant of water is about 73, compared to about 4 for common circuitboard materials.
• The decay constant is a function of the material's relative dielectric constant and its bulk resistivity.
• This medium is a dielectric with relative dielectric constant > 1, and is diamagnetic, with relative magnetic permeability < 1.
• Because of its high relative dielectric constant ( ~ 80 ), deionized water is also used ( for short durations, when the resistive losses are acceptable ) as a high voltage dielectric in many pulsed power applications, such as the Sandia National Laboratories Z Machine.
• The interconnect impedance that can be selected is constrained by the impedance of free space ( ), a geometric form factor and by the square root of the relative dielectric constant of the stripline filler ( typically FR-4, with a relative dielectric constant of ~ 4 ).
