A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.
