Dissipation factor - Wikipedia
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" or durability of oscillation.
Dielectric loss - Wikipedia
In electrical engineering, dielectric loss quantifies a dielectric material's inherent dissipation of electromagnetic energy (e.g. heat). [1] It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan(δ).
1.1.1. Loss Tangent and Dissipation Factor - Intel
Loss tangent (tan (δ)) (also referred to as dissipation factor (Df) by many PCB manufacturers) is a measure of signal attenuation as the signal propagates down the transmission line. This attenuation is the result of electromagnetic wave absorption in the dielectric material and is commonly known as dielectric loss.
损耗因子 - 百度百科
损耗因子又称损耗因数、阻尼因子 (damping factor)或内耗 (internal dissipation)或损耗角正切 (loss tangent)，是每周期耗散能量与在一周期内的最大贮能之比。.

18.9: Loss in Dielectrics - Engineering LibreTexts
2023年8月24日 — There are two main forms of loss that may dissipate energy within a dielectric. In conduction loss, a flow of charge through the material causes energy dissipation. Dielectric loss is the dissipation of energy through the movement of charges in an alternating electromagnetic field as polarisation switches direction.
amount of energy loss from the material due to an external electric field. The term tan= is called loss tangent and it represents the ratio of the imaginary part to the real part of the complex permittivity. The loss tangent is also called by terms such as …
Dissipation Factor - Definition, Measurement, Variables - HZO
The dissipation factor, also known as the loss tangent or tan δ, is a vital parameter that measures the dielectric losses in electrical systems and components. It quantifies the energy dissipated as heat when an alternating current (AC) signal passes through an insulating material or a capacitor.
Dielectric Loss Mechanism in Electromagnetic Wave Absorbing …
Conductive loss or conduction loss is caused by the fact that when EM wave propagates in absorbers, their energy will be converted into electric current. During the transmission of electric current along EM wave absorbers, their instinct resistance will generate joule heat and thus consuming EM wave energy.
Dielectric Loss Tangent - an overview | ScienceDirect Topics
The dielectric loss tangent (tan δ) of a material denotes quantitatively dissipation of the electrical energy due to different physical processes such as electrical conduction, dielectric relaxation, dielectric resonance and loss from non-linear processes [4].
