Editing Loss (section)

==Mathematics, science, and technology==
*[[Angular misalignment loss]], power loss caused by the deviation from optimum angular alignment
*[[Bridging loss]], the loss that results when an impedance is connected across a transmission line
*[[Coupling loss]], the loss that occurs when energy is transferred from one circuit, optical device, or medium to another
*[[Insertion loss]], the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber
*[[Dielectric loss]], a dielectric material's inherent dissipation of electromagnetic energy
*[[Loss function]], in statistics, a function representing the cost associated with an event
*[[Path loss]], the attenuation undergone by an electromagnetic wave in transit from a transmitter to a receiver
**[[Free-space path loss]], the loss in signal strength that would result if all influences were sufficiently removed having no effect on its propagation
*[[Return loss]], the ratio of the amplitude of the reflected wave to the amplitude of the incident wave
*[[Round-trip loss]] in laser physics refers to energy lost due to scattering or absorption
*{{ill|Switching loss|de|Schaltverluste}}, power loss incured due to circuit switching
