Dielectric loss, often denoted as tanδ, characterizes the energy dissipated as heat in a dielectric material when subjected to an alternating electric field. This dissipation arises from internal friction within the material as its constituent particles endeavor to align with the changing electric field direction. Quantified as the ratio of dissipated energy to stored energy, dielectric loss is a vital parameter in electrical engineering. It signifies the conversion of electrical energy into heat and is particularly significant in the design of components like capacitors and insulators. Reducing dielectric loss is imperative for optimizing the efficiency and functionality of electrical systems,  especially in applications demanding precision and minimal energy expenditure.
