We spot on the performance of two acceleration data structures for electromagnetic ray tracing purposes on GPU using the CUDA programming language, namely the KD-tree and the SBVH. Our implementations have been based on the approach made available by NVIDIA which takes into account for the programming optimizations made possible by the latest version of CUDA and for the latest NVIDIA GPU architectures.

In this paper, we present a novel chaotic hybrid DPSK-MPPM modulation technique which is ultimately secure, spectrally efficient, and highly detection-sensitive. The position and phase information are perturbed by two variables of 2D chaotic map. The BER performance of the proposed scheme is then evaluated numerically and compared with that of the CPPM.

A fan-shaped ultra-wideband (UWB) antenna with triple filtering function is proposed by using a L-shaped slot (LSS), a U-shaped slot (USS) and a U-shaped resonator (USR). This antenna structure is comprised of a 50-Ohm transmission line with a defected microstrip structure, a LSS, a USR, a ground plane and a fan-shaped radiation patch. The antenna is simulated by using HFSS based on FEM, and the results show that the antenna covers the entire UWB band and can filter out three unwanted narrowband interferences, making it suitable for band-notched UWB communication applications in practical engineering.

Wireless sensor network (WSN) as part of far field energy harvesting system has been designed and implemented to detect failures in the distribution power lines due to natural disasters. Far field energy harvesting system used in detection of the failures for power lines involve antenna, rectifier, and impedance matching sections. The sensor system which is powered by the energy harvesting system using the ambient energy in the ultra-high frequency range (UHF) is tested for various different conditions.

Environmentally adaptive error recovery (EAER) technology for wireless communication was developed to reduce the number of communication errors and the time needed for recovery in industrial wireless networks. EAER adapts the communication frequency to the radio environment by changing the radio frequency to a better one when communication errors occur by pre-measuring the radio environment at each slave. The pre-measurement is done by having slaves measure the radio environment using test signals sent by the master. EAER was able to continue the communication within three super frames when a noise signal was applied to a communication channel.

Design of a sensor network system for maintaining safety in an industrial setting using energy harvesting interfaced with multiple antennas is given. The practical implementation, low interference, and high accuracy make this type of system ideal for industrial safety and automation applications. The sensor network system that operates at 5.8 GHz can be subject to modification based on communication bands in the area as well as accuracy needs.

The effects of adding annular slots to solid conical antenna is described in this paper. The slots produced stop-bands with anti-resonant frequencies that are inversely proportional to the depth of the slots. The addition of double slots produced two distinct stop-bands. Prototype antennas were fabricated and measured to verify the simulated results.
