In this work we propose a method based on 3D electromagnetic simulations to design and optimize Wireless Sensor Network (WSN). We investigate the performance of WSN based on ZigBee modules for the application of collecting the data obtained from sensors distributed inside a research rocket. The propagation conditions inside the rocket are simulated and optimized using commercial 3D electromagnetic...
This paper presents a comprehensive experimental study of barely visible impact damage detection for carbon-fibre reinforced polymer (CFRP) composites using an electromagnetic sensor: coupled spiral inductors. A multi-frequency inspection is performed, where the resultant images indicate its great potential for the evaluation of damage propagation. The accuracy and efficiency are compared with the...
As a result of constant technological progress over the last several years a rapidly increasing number of used computers, various types of electronic devices and telecommunications equipment. HPEM impulses are increasingly being used to disrupting or even destroy electronic devices. The article presents a modification of the construction of the reflector antenna of HPEM generator increases the intensity...
The ubiquity of WLAN networks bears inherently a risk of generating considerable interference level. Measurements have been obtained to demonstrate that densely, though randomly deployed Access Points cannot operate at maximum bit rates due to mutual interference. A simple non-collaborating algorithm has been proposed and verified under carefully controlled measurement conditions providing a proof...
