WebIn physicsand engineering, the quality factoror Qfactoris a dimensionlessparameter that describes how underdampedan oscillatoror resonatoris. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radianof the cycle of oscillation.[1] The Q factor determines the qualitative behavior of simple damped oscillators. (For mathematical details about these systems and their behavior see harmonic oscillator and linear time invariant (LTI) system.) • A system with low quality factor (Q < 1⁄2) is said to be overdamped. Such a system doesn't oscillate at all, but when displaced from its equilibrium steady-state output it returns to it by expo…
Most resonant cavities are made from closed (or short-circuited) sections of waveguide or high-permittivity dielectric material (see dielectric resonator). Electric and magnetic energy is stored in the cavity and the only losses are due to finite conductivity of cavity walls and dielectric losses of material filling the cavity. Every cavity has numerous resonant frequencies that correspond to ele… WebD denotes dissipation factor and Q is quality factor. The loss tangent tan d is called tan delta, tangent loss or dissipation factor. Sometimes the term “quality factor or Q-factor” is used with respect to an electronic microwave material, which is the reciprocal of the loss tangent. For very low loss materials, since tan d ≈ d, the loss
