==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 , power loss incured due to circuit switching Lick Observatory Supernova Search (LOSS) program
