Anomalous Skin Effect

Experimental values of the monochromatic, near normal emittance, ελN, of gold at cryogenic temperatures are presented and compared with values predicted by existing theoretical models. From this comparison recommendations are made regarding the engineering suitability of these models. Data obtained by the present authors for ελN of gold in the wavelength range 1 to 30μ and at temperatures of 300, 79, and 6.0 K are compared with the Drude free electron model, the anomalous skin effect theory for both specular and diffuse electron reflections, and the Holstein quantum mechanical model. Results show that the anomalous skin effect model with diffuse electron reflections predicts ελN most accurately. At room temperature and at liquid nitrogen temperature the agreement between this model and the data is within 5 percent. At liquid helium temperatures the agreement is somewhat poorer, i.e., within 30 percent.

Anomalous Skin Effect

The radiative transfer between two infinite parallel metallic surfaces separated by a nonconducting ideal dielectric is calculated on the basis of electromagnetic wave theory. The solution is restricted to the case of large spacing (thick film) wherein the effects of interference and radiation tunneling can be neglected. The optical properties of the metals are predicted via the anomalous skin effect theory, the Drude single electron theory and the Hagen-Rubens relation. A comparison of the predicted radiative fluxes indicates the large disparities which result from the three different specifications of the optical properties of metals. For practical applications at cryogenic temperatures, approximations are obtained for the thick film solution using the anomalous skin effect theory of the optical properties.

The anomalous skin effect arises in good conductors at low temperatures and high frequencies when the electronic mean free path becomes comparable with or greater than the classically calculated skin depth. Measurements have been made on a number of metals at frequencies of 1200 and 3600 Mc/s, and the form of variation of r. f. surface conductance with d. c. conductivity agrees well with that predicted theoretically by Reuter & Sondheimer, assuming that the electrons are scattered diffusely when they hit the surface of the metal. From the results, estimates are made of the effective value of σ/ l , the ratio of d. c. conductivity to mean free path, and hence of the free surface area of the occupied region of k -space. The estimate for copper agrees well with that expected theoretically; those for silver and gold are rather lower than the theoretical values. For the other metals investigated, tin, cadmium, lead and aluminium, no theoretical estimates are available. The results are very sensitive to the presence of surface imperfections; the effect of these is discussed.
