When a dielectric is inserted between the plates of a parallel-plate capacitor, it increases the capacitor's capacitance, i.e., its ability to store opposite charges on each plate. However, this doesn't happen when the capacitor plates are separated by a vacuum. This is why the dielectric ...
What is a dielectric star diagonal? Using a Telescope: The piece of a telescope is critical tot he viewing experience, while some eye pieces in a straight line from the aperture, and others extending from the side of the telescope. Depending on the orientation of the telescope this can make...
Maintaining dielectric resistance is critical for impedance and signal integrity concerns, as the insulating material must keep the circuit working correctly. Enhancing dielectric strength protects the circuit board’s long-term function. The safety and effectiveness of a device with a circuit board rely...
The nuances of different capacitor types are, for the most part, determined by the characteristics of the dielectric used and the method by which a given device is constructed. All dielectric materials have limitations, with regard to the maximum applied field they can withstand for a given mater...
Avacuum circuit breakeruses a vacuum as the arc quenching medium. The vacuum has veryhigh dielectric strengthand very low arcresistance. The contacts are enclosed in a ceramic or metal chamber that is evacuated to very low pressure. When the contacts open, the arc is initiated in the vacuum ...
For AlN ceramics, more attention and research are focused on their thermal conductivity. As a ceramic material with integrated structure and function, its dielectric properties should also receive sufficient attention. The energy transmission window of high-power microwave tubes should have characteristics...
The Fresnel Equations describe the reflection and transmission of light at the interface between two different mediums. Introduced by Augustin-Jean Fresnel, they explain how light behaves as a transverse wave. When light hits the surface of a dielectric, it reflects and refracts depending on the ...
Electrostatics: This is the sub-field of electromagnetics describing an electric field due to static (non-moving) charges. As an approximation of Maxwell’s equations, electrostatics can only be used to describe insulating, or dielectric, materials entirely characterized by electric permittivity. When...
Liquid immersion cooling is a thermal management technology in which electronic components, such as servers or other hardware, are entirely submerged in a dielectric fluid, typically non-conductive and engineered to efficiently absorb and transfer heat away from the components. The process involves the...
Dielectric testing is a method for testing the insulating properties of an object. This helps ensure that items are safe for...
