We present an infrared thermal emitter that exhibits unequal emissivity and absorptivity for a given frequency and angle of incidence, violating Kirchhoff’s law of thermal radiation. We exploit spatio-temporal modulation of the … WebWhat is Kirchhoff's law formula? Kirchhoff's Current Law (KCL) states that the sum of all currents leaving a node in any electrical network is always equal to zero. It is based on the principle of conservation of electric charge. The law is also referred to as Kirchhoff's first law. In formula form this is given by: n∑i=1Ii=0.
