This paper describes the implementation of mode-stirred method for susceptibility testing according to the current DO-160D standard. Test results on an Engine Data Processor using the implemented procedure and the comparisons with the standard anechoic test results are presented. The comparison experimentally shows that the susceptibility thresholds found in mode-stirred method are consistently higher than anechoic. This is consistent with the recent statistical analysis finding by NIST that the current calibration procedure overstates field strength by a fixed amount. Once the test results are adjusted for this value, the comparisons with the anechoic results are excellent. The results also show that etst method has excellent chamber to chamber repeatability. Several areas for improvements to the current procedure are also identiified and implemented.

The definitive reference on electromagnetic shielding materials, configurations, approaches, and analyses This reference provides a comprehensive survey of options for the reduction of the electromagnetic field levels in prescribed areas. After an introduction and an overview of available materials, it discusses figures of merit for shielding configurations, the shielding effectiveness of stratified media, numerical methods for shielding analyses, apertures in planar metal screens, enclosures, and cable shielding. Up to date and comprehensive, Electromagnetic Shielding: Explores new and innovative techniques in electromagnetic shielding Presents a critical approach to electromagnetic shielding that highlights the limits of formulations based on plane-wave sources Analyzes aspects not normally considered in electromagnetic shielding, such as the effects of the content of the shielding enclosures Includes references at the end of each chapter to facilitate further study The last three chapters discuss frequency-selective shielding, shielding design procedures, and uncommon ways of shielding—areas ripe for further research. This is an authoritative, hands-on resource for practicing telecommunications and electrical engineers, as well as researchers in industry and academia who are involved in the design and analysis of electromagnetic shielding structures.

The contemporary military rivalry is driven mostly by the ongoing military technical revolution. In particular, the weapons used on the future battlefield will play an important role in military affairs. Which weapons can play a key role in the future? Electromagnetic weapons seem to involve key elements for the future battlefield; they offer advantages over conventional weaponry by providing nonlethality, the advantage of attack at the speed of light, fast engagement of multiple targets, potentially low operational cost, and wide-area coverage for offensive and defensive purposes. This thesis proposes hypothetical electromagnetic bombs (e-bomb) and classifies e-bombs into three isocategories depending on power sources. It also assesses the potential lethality effects on different targets based on a developed MATLAB Simulation Model. It also provides an understanding of the principles of High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Weapons. In addition, a measure of effectiveness model is proposed to compare the hypothetical e-bomb, HEMP and HPM weapons. The strategic effects on military affairs will be assessed. Finally, this study will help the Turkish Armed Forces decide on investment in e-bomb research and development (R&D) to improve combat capabilities in the future battlefield.
