Electromagnetic compatibility (EMC) is a key issue in the design and development of safe and effective medical instruments. The treatment probes of high intensity focused ultrasound (HIFU) systems not only receive and transmit electromagnetic waves, but also radiate ultrasound waves, resulting in electromagnetic coupling. In this paper, an electromagnetic shielding method involving the enclosur...

BACKGROUND The objective of this study is to investigate electromagnetic compatibility (EMC) of implantable neurostimulators with the emissions from radio frequency identification (RFID) emitters. METHODS Six active implantable neurostimulators with lead systems were tested for susceptibility to electromagnetic fields generated by 22 RFID emitters. These medical devices have been approved for...

This paper presents results of electromagnetic compatibility (EMC) testing of three implantable neurostimulators exposed to the magnetic fields emitted from several walk-through and hand-held metal detectors. The motivation behind this testing comes from numerous adverse event reports involving active implantable medical devices (AIMDs) and security systems that have been received by the Food a...

This work is concerned with the parallelization of the multilevel fast multipole algorithm (MLFMA) for large scale electromagnetic simulations on distributed memory computers. We focus on techniques suited for low-cost clusters of workstations (COWs) and computational GRIDs. These consist of a number of nodes interconnected through a Gigabit Ethernet network and a fast switch. The algorithm is ...

The continuous scaling of CMOS circuits has set the MOSFET transistor in the nanoelectronic era. In this context, the functionality and complexity of integrated circuits (ICs) are growing up. However, the operation voltage has been continuously reduced. The higher complexity of ICs has allowed including electronic systems in a lot of safety critical applications (i.e., automotive, aeronautics a...

Introducing Electromagnetic Interference and Electromagnetic Compatibility, or “The Art of Black Magic”, for engineering students might be a terrifying experience both for students and tutors. Removing the obstacle of large, expensive facilities like a fully fitted EMC laboratory and hours of complex theory, this paper demonstrates a design of a laboratory setup for student exercises, giving st...

This paper deals with the use of two main standard modeling approaches in order to control the electromagnetic compatibility of an IC before manufacturing. An application is given in the case of a complex mixed circuit which is an Analog to Digital Converter (ADC) embedded in a microcontroller. The digital core (DC) of the microcontroller consumes dynamic currents which generate internal distur...
