Identification problem in a multiple access channel is being studied. Such problem arises, for example, in analysis of monitoring systems using the surface acoustic wave (SAW) radio tag (label). The SAW radio tags are the passive wireless units which can be used in different application with extreme environment factors (high temperature, radiation, etc). The mathematical model of radio tag is assumed to be a linear time-invariant filter. A receiver (reader) observes the sum of the K linear filters responses to an interrogation signal. A combination of K filters are chosen arbitrary from the known set of M known filters, rs, K << M. Receiver determines the filter combination according to the sum response received. The problem of the design of the radio label impulse responses under some constraints is studied. © Springer International Publishing Switzerland 2014

The electromagnetic properties of electrically small loop antennas for two different applications are discussed: near-filed and far-field RFID systems. In the first case miniature loop antennas are designed for the near field wireless biological and medical sensing application. The magnetic field in the near-field zone is used for coupling between the loops. Using regularly placed capacitors between segments of the loop provides a homogeneous current distribution along the electrically small loop resulted in the improved magnetic coupling. In another case the loop antenna with the improved radiation characteristics is designed for far distance RFID reader antenna. The antenna consists of a combination of the noninteracting loop and dipole. Such a combination shows a cardioid-type radiation pattern and doubled antenna gain. Results of simulations and measurements of test structures of the loop antennas are presented. © 2015 IEEE.

Influence of electromagnetic parameters of biological medium on the propagation of electromagnetic waves radiated by an antenna implanted in the human body is under consideration. The problem of refraction on the boundary between the biological medium and the free space is analytically solved taking into account the complex dielectric permittivity of the human body. Modeling the electromagnetic wave propagation through this boundary revealed a high attenuation of the wave radiated by an implanted antenna, which was experimentally observed. The considerable attenuation of the radiated waves is conditioned by the total internal reflection at the interface between the two dielectric layers and by the dielectric loss in the biological tissue. The proposed analytical model was confirmed by the full-wave simulation using SEMCAD X by SPEAG and the experimental validation. © 2015 EuMA.

We look for materials with good SAW resonator properties and with the largest difference between temperature responses of resonators in a pair on a single substrate. We have identified several cuts of quartz having useful properties with TCF difference up to 140 ppm/°C for a pair of resonators on a single substrate. As a rule, placing of such resonators on a single substrate requires rotation by up to 90° relative to each other thus increasing the die size. The limited range of cuts presents a unique opportunity to place both resonators along the X+90° direction with one resonator using BGS waves (with electrodes placed along X axis) and the other one (with electrodes inclined by about ±10° to X axis) using Rayleigh waves. These cuts are close to the 70°Y-cut where high TCF difference is reached together with acceptable characteristics of resonators. Resonators were designed for all useful cuts (including the 70°Y-cut) and tested. The use of different periods in reflectors and IDT together with individual choice of gaps between reflectors and IDT allowed obtaining low spurious content in resonator responses. The quality factors reached values up to 4000 at central frequencies around 915 MHz for both BGS and Rayleigh types of waves. The measured difference of TCF is about 138 ppm/°C on 70°Y-cut that is close to the calculated value. © 2014 IEEE.

A software system for a simulation model of a UAV's automatic landing system is presented herein. The simulation model allows us to determine the level of influence of different distortions of the observed image on the UAV's landing accuracy. The correlation extremal system of terminal guidance (CESTG) of an unmanned aerial vehicle (UAV) executed on the basis of an optoelectronic sensor has found its application as a tool providing the terminal delivery of UAV's freight to the planned Earth surface area or automatic landing of an unmanned helicopter (UH) on a selected place or on a surface ship deck. In operation, the CESTG carries out a search for a landing place (freight delivery), guidance to the selected landing place (freight delivery) at the UAV's approach and the exact path of the UAV to the selected area in the processing of current information receiving at the discrete moments of time (shot shaping time) about the surveillance area from the optoelectronic sensor. © 2011 IEEE.

The efficiency of electromagnetic power reradiation by a wirelessly interrogated passive sensor and its sensitivity to the measured value are the main factors defining the sensor performance. The analysis gives the relation between the re-radiation efficiency and the electromechanical coupling factor. Experimental resonator parameters demonstrate the relevance of this efficiency improvement. The calculation of the coupling factor simultaneously with the temperature coefficient of delay for all quartz orientations was carried out. The results of this calculation can help to select optimal trade-offs between the sensitivity and the efficiency of power re-radiation. © 2016 IEEE.
