Comments on "Measurement of the microwave conductivity of a polymeric material with potential applications in absorbers and shielding"

For original paper see K.Naishadham and P.K.Kadaba, ibid., vol.39, pp.1158-64 (1991). Naishadham and Kadaba demonstrated the utilization of polyacetylene and PBT conductive polymers as single-layer, double-layer electric Salisbury screens and EMI shields. In this article the authors comment on some inconsistencies that were found between the calculated results and the assumptions stated. A reply by Naishadham and Kadaba is included.
