Dispersive behaviour of humid anisotropic media
The results of dielectric measurements on a humid system consisting of filter papers which show strongly anisotropic properties in the planes and normal to the planes of the sheets, are reported. Configurations were used in which the flow of current is, respectively, normal to and in the planes and these show distinctively different behaviour. Transport in the planes provides some of the best examples of LFD ever seen by us, extending over up to eight decades of frequency; transport across the planes is influenced by less dispersive behaviour which is ascribed to the fibre-fibre contacts.
