In both industrial and domestic environments, there will be a large increase of wireless communication systems. The density of wireless devices and need of additional bandwidth is expanding which is increasing the wireless interference. Interference emerges from unintended radiators is the main cause of degrading the Electromagnetic Compatibility and wireless communication performance in near f...

BACKGROUND The use of radio frequency identification (RFID) systems in healthcare is increasing, and concerns for electromagnetic compatibility (EMC) pose one of the biggest obstacles for widespread adoption. Numerous studies have demonstrated that RFID systems can interfere with medical devices; however, the majority of past studies relied on time-consuming and burdensome test schemes based on...

A multiphase study examining electromagnetic compatibility (EMC) between wireless digital telephones and hearing aids has been under way at the University of Oklahoma EMC Center since May 1995. In a phase 1 clinical study involving 68 hearing aid wearers, interference varied significantly by telephone technology, hearing aid type, and hearing loss characteristics. More than 80 percent of the te...

Nowadays electromagnetic environment is rapidly expanding in frequency domain and wireless services extend in terms of covered area. European electromagnetic compatibility regulations refer to limit values regarding emissions, as well as procedures for determining susceptibility of the vehicle. Approval procedure for a series of cars is based on determining emissions/immunity level for a few ve...

In this study, two types of direct interface capacitive sensors, self- and mutual-capacitance, were developed and compared experimentally. Electromagnetic Compatibility (EMC) tests-International Electrotechnical Commission (IEC) 61000-4-3, IEC 61000-4-4, IEC 61000-4-6-were applied in an accredited laboratory to measure the immunity of the sensors against radiated and conducted interference. The...

Many efforts were made in the last years in order to develop new techniques for mobile objects identification, location and tracking. Radio Frequency Identification (RFID) systems are a possible solution to this problem. There are many different practical implementations of such systems, based on the use of radio waves from low frequencies to high frequencies. In this chapter we present a short...

Establishment of signal integrity over a broad band as well as suppression of electromagnetic coupling between wirings in ICs are significant problem, because packaging density in ICs is very high. To clarify the electromagnetic compatibility (EMC) problems that related to the interconnection in the IC chip, transmission characteristics and electromagnetic coupling between wirings in the specia...

The design requirements of induction hobs are strongly restricted by efficiency, heating performance, cost, the generation acoustic noise, and electromagnetic compatibility (EMC). These two latter topics, cost EMC, motivated research presented in this article. different levels at which equivalent load hob is excited generate a variation impedance throughout grid period even if all other paramet...

This paper presents experimental testing that has been performed on wireless communication devices as victims of electromagnetic interference (EMI). Wireless victims included universal serial bus (USB) network adapters and personal digital assistants (PDAs) equipped with IEEE 802.11b and Bluetooth technologies. The experimental data in this paper was gathered in an anechoic chamber and a gigahe...

Electromagnetic compatibility (EMC) is defined as the capability of equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable disturbances anything that same [1]. EMC regulatory requirements for instrumentation and control (I&C) were not developed effect until last few years. Therefore, there a considerable number plant has been qualif...
