“…Although the negative dielectric constant is a new discovery in physic since year 2000 but the mechanism of this material is still not clear. [27][28][29] Negative value of dielectric constant will give rise to minimum transmission and maximum absorption that indicated good microwave absorbing property as reported by Smith et al (2000). 30 Since the negative value of dielectric constant is a new discovery in physic since year 2000 and the mechanism of this material is still not clear, it is very difficult to explain why the negative dielectric constant is obtained at lower synthesis temperature instead of positive value.…”

As a nano-material possessing moderate conductivity, magnetic and dielectric property, novel hexanoic acid doped polyaniline (PAni/HA) micro/nanocomposites containing TiO 2 and Fe 3 O 4 were prepared by template free method under various polymerization conditions. FT/IR spectra of PAni/HA/TiO C. PAni/HA polymerized at low temperature exhibited higher conductivity (1:0 Â 10 À3 S/cm) compared with PAni/HA polymerized at higher temperature (7:0 Â 10 À4 S/cm). The conductivities of the PAni/HA/TiO 2 and PAni/HA/TiO 2 /Fe 3 O 4 were relatively low (3:3{4:2 Â 10 À4 S/cm) after addition of TiO 2 and Fe 3 O 4 . PAni/HA/TiO 2 /Fe 3 O 4 micro/nanocomposites synthesized at 0 C exhibited higher magnetization (Ms = 7.7 emu/g) compare with micro/nanocomposites that synthesized at 25 C (Ms = 4.7 emu/g). TGA characterizations of the micro/nanocomposites were also being discussed in this paper.

Abstract-New possibilities to design artificial magnetic materials for microwave frequencies are considered. Such composites can be used in microwave engineering at frequencies where no natural lowloss magnetic materials are available. A new magnetic particle (metasolenoid) formed by a stack of many parallel and very closely spaced single broken loops is proposed and analyzed analytically, numerically, and experimentally. It is shown that the effective permeability can reach reasonably high values over a wide frequency range when using such inclusions.
