Abstract

Percolation phenomena were studied in a series of six composites with a cellular structure. Measurements made on the composites include dc and ac electrical conductivity, dielectric constant, 1/for flicker noise and magnetoresistance. Results arising from these extensive measurements were fitted to the percolation power laws and a phenomenological equation to give various exponents, which are presented, discussed and compared.
