Polydimethylsiloxane-multiwalled carbon nanotube composite as a metamaterial
Abstract(#br)Negative permittivity is an exceptional property of metamaterials, which makes them unique class of artificial materials with numerous applications ranging from cloaking to wave filters. In this paper we report about the PDMS (Polydimethylsiloxane)–MWcnt (Multi wall carbon nano tube) composite beyond percolation, as a metamaterial with high negative permittivity. Percolated composite showed high negative permittivity of −2376.62 at 2541.401\u003cce:hsp sp=\"0.25\"/\u003eHz and low tangent loss of −0.065 at 1\u003cce:hsp sp=\"0.25\"/\u003eMHz.
