In this paper a solution to integrate video surveillance into RFID units for remote scene monitoring is proposed. The method is comprised of two major building blocks, namely an RFID transmitter operating at 240 kbps, and a very low complexity image compression engine. The latter is realized with field programmable gate array (FPGA) using small amount of gate count and no external memory.
This paper proposes a new constitutive relation for a synthetic chiral material composed of a large number of small helices embedded in host media. All helical inclusions are arranged with same orientation (e.g., z-direction) and are assumed to have a negligible pitch angle. In other words, the far fields generated by such helices will not produce z-direction components regardless of polarization...
The efficient analysis of wire antennas of arbitrary shape is presented. The exact kernel representations of Green's function are given in place of the thin-wire approximation kernel for the moment method solution of arbitrary wire antennas and scatterers with moderately large radius. The kernel expressions are exactly expanded on the basis of series summations so that the elements of the impedance...
