“…The fabrication of thin conductive and partially conductive coatings is a common practice in a number of engineering areas. Their employment spans from electronic circuitry for the fabrication of thin-film transistors [67], printed resistors [69,70] or transparent electrodes [68] to shielding or absorbing materials [11,12,16] for applications in Electro-Magnetic Interference (EMI) [71] and Electrostatic Discharge (ESD). Non-perfect conductive thin films can be synthesised through a wide set of materials.…”

An overview of transmission/reflection-based methods for the electromagnetic characterisation of materials is presented. The paper initially describes the most popular approaches for the characterisation of bulk materials in terms of dielectric permittivity and magnetic permeability. Subsequently, the limitations and the methods aimed at removing the ambiguities deriving from the application of the classical Nicolson-Ross-Weir direct inversion are discussed. The second part of the paper is focused on the characterisation of partially conductive thin sheets in terms of surface impedance via waveguide setups. All the presented measurement techniques are applicable to conventional transmission reflection devices such as coaxial cables or waveguides.

Koaksiyel tutucu metot, yankısız odaya nispeten daha pratik ölçüm imkânı sunsa da, özellikle ölçüm yapılabilen frekans aralığının sınırlı olması ve araştırmacıların daha pratik test yapabilme istekleri bu çalışmanın gerekçesi olmuştur.…”

Modern technology has advanced swiftly, and thus, people have higher and higher demands for functional textiles. In order to have textiles with electromagnetic shielding effectiveness (EMSE) and far infrared emissivity, in this research, we fabricated three types of bamboo charcoal/metal (BC/M) complex yarns with metal wires as the core yarn and bamboo charcoal textured yarn as the wrapped yarns, with a rotor twister machine. Two manufacture parameters for the complex yarns were rotor speed (8000 rpm) and wrapped number of the BC/M complex yarns (4 turns/cm). BC/M complex woven fabrics were made of cotton yarn (warp yarn) and BC/M complex yarns (weft yarns), using a loom machine. The surface resistivities of BC/M complex woven fabrics were first measured. Then, EMSE evaluation was performed to test BC/M complex woven fabrics with different lamination angles. The BC/M complex woven fabrics exhibited higher surface resistivity than other woven fabrics by 1.71 × 10 10 Ω/Sq; and the EMSE was 50-60 dB when the lamination number was 6 at incident frequencies between 1.83 and 3 GHz, which was satisfactory.
