Measurements of far infrared transmission and reflection have been done on composites consisting of small tin particles (approximately 250A radius) embedded randomly in an insulating matrix of KCl, with volume fraction of tin ranging from 0.001 to 0.03. These experiments measure the optical properties from 3 cm/sup -1/ to 50 cm/sup -1/ and at temperatures from 1.7K to 27K, thus covering the energy gap frequency and the transition temperature of the tin. The results of these experiments show an enhanced absorption around the gap frequency at superconducting temperatures.
