Abstract :
Lumped Element Kinetic Inductance Detectors (LEKID), when coupled with a silicon lens, have very high absorption efficiencies (70%) over more than one octave frequency band. In this contribution we introduce a theoretical derivation of the power received by these detectors by modeling them as an infinite array of dipoles. The theoretical model has been validated by measurements on a prototype working in the microwave band.
