“…It is a number relating the ability of the material to carry alternating current to the ability of vacuum to carry alternating current [48]. The dielectric constant is an essential information when designing capacitors and in other circumstances, where a material is expected to introduce capacitance into a circuit, allowing for the accurate circuit design of devices able to be used in a radar, RF admittance, or capacitance technologies [49][50][51][52]. The effect of V f of PANI on ε r of SBS/PANI blends, was studied at two different temperatures, equal to 298 and 348 K. Results are shown in Fig.…”

Styrene-butadiene-styrene triblock copolymer (SBS) blends were prepared using different weight ratios of conducting polyaniline (PANI). Several electrical properties such as volume resistivity, dielectric constant, dissipation factor and alternating current conductivity of the blends were studied pointing to understand the influence of different parameters like PANI concentration, frequency, and temperature on these properties. The prepared materials present a slight reduction in volume resistivity as a function of temperature, being useful in conditions where the temperature control is hard. More than this, dielectric constant tests allowed inferring that among tested samples, the one filled with 45 wt % of PANI is potentially able to be used in the electromagnetic dissipation field. Finally, the alternating current tests allowed to prove that the electrical conduction of the blend is mainly dominated by ionic transportation. Therefore, prepared materials can be considered as a strategic, low-cost, environmentally friendly material which can be used in various border fields.

Active Radar Cross Section Reduction of an Object Using Microstrip Antennas

The research performed in this paper suggests that the radar cross section of an arbitrarily shaped object can be reduced by canceling the scattering from the object with the radiation from an antenna (implemented here as a microstrip antenna) placed on the surface of the object. Assuming that the direction of arrival of the incident signal is known, the radiation from the defending antenna can be adjusted in real‐time to cancel the scattering from the object in order to produce a negligible total field at the distant receiver so that the object becomes invisible to a monostatic radar working in a given known frequency band. This is implemented using an analog sensor on the object to measure the time domain field on the object, which is then connected to the antenna through an amplifier and phase shifter to control the radiation from the patch antenna. The system is implemented in real time and does not require any digitization or signal processing. The radar cross section reduction can thus be achieved with a wide variety of incident signals in the prescribed frequency band.
