В данной статье проводится исследование функционирования автономной коллаборации беспилотных летательных аппаратов (БПЛА), основанной на децентрализованно-организованном управлении. В основе коллаборации положен роевой интеллект с использованием мультиагентного подхода. Выявляется оптимальная стратегия группового управления, на основе которой формализуется коллаборация агентов и определяется информационное взаимодействие (ИВ) между элементами системы. На основе разрабатываемых моделей выявляются уязвимости в ИВ элементов, и разрабатываются меры защиты от деструктивного информационного воздействия (ДИВ), основанные на классических подходах к обеспечению информационной безопасности (ИБ). Данное исследование проводится с целью теоретического обоснования возможности реализации самоорганизующейся группы БПЛА для ее последующей разработки и внедрения в различные сферы гражданской деятельности.

Operating up to 3.2-GHz with power consumption of 1.32mW, a Phase Controlled Current Source (PCCS) capable of both phase frequency comparing and current providing is presented. Benefiting from simple, feed-forward operation characteristic, the PCCS minimizes the short current issue while maintaining free dead zone feature. The phase and frequency sensitivities of the PCCS have been measured to demonstrate its performance. With a reference source ranging from 2.1-GHz to 3.2-GHz, a PLL embedding the PCCS achieves phase noise around −100 dBc/Hz at 1-kHz offset. The lowest phase noise at 1MHz offset is −131 dBc/Hz when the PLL uses a 2.3-GHz reference source.

Guided-wave single-mode propagation of sub-ps terahertz (THz) pulses in a plastic photonic crystal fiber has been experimentally demonstrated for the first time to the best of our knowledge. The plastic photonic crystal fiber is fabricated from high density polyethylene tubes and filaments. The fabricated fiber exhibits low loss and relatively low dispersive propagation of THz pulses within the experimental bandwidth of 0.1 /spl sim/ 3 THz. The measured loss and group velocity dispersion are less than 0.5 cm/sup -1/ and -0.3 ps/THz/spl middot/cm above 0.6 THz, respectively.

In this paper, we discuss the control and suppression of spurious resonances commonly encountered with distributed bandpass filters. The basic idea consists of introducing low-pass structures within bandpass topologies. By adjusting low-pass filter cutoff frequencies, harmonic resonances are attenuated, while maintaining in-band performances. In addition, transmission losses may be reduced as the insertion technique leads to optimum designs in terms of overall size. The approach described here is based upon the combination of classical synthesis techniques and optimization procedures provided by conventional computer-aided-design tools. Experimental results are obtained in the case of /spl lambda//sub g//4 shunt-stub filters implemented in classical semilumped low-pass architectures. Then, we investigate alternative integration technologies and techniques to improve the out-of-band rejection over very wide operating bandwidth. To overcome some design limitations, i.e., workable characteristic impedance value, we propose and validate a multilayer solution. Finally, new low-pass topologies are suggested to improve low-pass filter band rejection.

The TM/sub 0/ parallel-plate mode field that is radiated from the currents induced on a covered microstrip transmission line by a finite-gap voltage source is studied. The behavior of the total radiation field (the field radiated by the total strip current) is investigated, along with the field radiated by the constituent current components that make up the total current, namely the bound-mode (BM) and continuous-spectrum currents. The continuous-spectrum current is further resolved into the sum of a physical leaky-mode current and a residual-wave current, and the fields radiated by each of these separate components are examined. It is determined that leaky-mode fields can contribute to crosstalk and other interference effects near the source and within an angular leakage region, while the radiation field from the BM current is the predominant mechanism for these effects further away from the gap source, outside the leakage region. The field radiated from the residual-wave current can be quite strong in the "spectral-gap region," which is the frequency region where the leaky mode is nonphysical, and therefore the leaky mode does not contribute directly to the spectrum of current on the strip in the decomposition used here.
