In the paper a planar circular model (20-by-20 µm in size) of a band-pass multiplexing filter, based on 2D photonic crystal with original “dewdrop-petal” inner structure has been considered. The frequency selectivity of this filter is due to its geometry, built on the base of nature processing physical system - a flower with dewdrops on its petals. The filter has been PCsimulated on TE electromagnetic...
Research is dedicated to the questions of electromagnetic compatibility of isotropic point antennas which are set on the current-conductive body of arbitrary form (for example, airplane). Frequency-spatial division of real antennas of air vehicle must be predicted by previous calculations. It is expedient to make them on the stage of airplane constructing. This approach allows to get a corresponding...
We consider new queueing model describing the operation of cyclic polling systems in very hight throughput wireless mesh-networks. Queues are cyclically polled by two servers. Some of queues are served by both servers, the rest are served just by one of them. To investigate the model, we apply the mean value analysis to derive the mean waiting times in queues and provide the numerical examples.
