capacitor loss tangent
1Loss tangent — The loss tangent is a parameter of a dielectric material that quantifies its inherent dissipation of electromagnetic energy. The term refers to the tangent of the angle in a complex plane between the resistive (lossy) component of an… …
2Dissipation factor — In physics, the dissipation factor (DF) is a measure of loss rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of Quality factor, which represents the quality of… …
3Relative permittivity — Relative static permittivities of some materials at room temperature under 1 kHz[1] Material εr Vacuum 1 (by definition) Air 1.00058986 ± 0.00000050 (at STP, for 0.9 MH …
4Microwave cavity — A microwave cavity is a closed metal structure that confines electromagnetic fields in the microwave region of the spectrum. Such cavities act as resonant circuits with extremely low loss at their frequency of operation. Their Q factor may reach… …
