Nov. 1, 2011 - PRLog -- Electromagetic Interface(EMI) is caused by undesirable radiated electromagnetic fields or conducted voltages and currents. The interference is produced by a source emitter and is detected by a susceptible victim via a coupling path involving conduction(electric current) / radiation (electromagnetic field) / capacitive coupling (electric field) / inductive coupling (magnetic field). Some typical external noise sources into a radio receiver include radiated electric field coupling from: high-voltage power lines, broadcast antennas, communication transmitters, vehicle ignition systems and electric machinery. Most conducted coupling from external sources occures through the ac power lines. Typical radio interface to other equipment includes radiated electric field couping to: TV sets, broadcast receivers, telephone lines, appliances, and communication receivers. Most conducted coupling to other equipment occurs through the ac power lines. The most common methods of noise reduction include proper equipment circuit design, shielding, grouding, filtering, isolation, separation and orientation, circuit impedence level control, cable design, and noise cancellation techniques. Electromagnetic compatibility(EMC) is  the ability of electrical and electronic systems to function in the intended operating environment without causing or experiencing performance degradation due to unitentional EMI. It is important that electronic equipment designs ensure performance in the expected electromagnetic environment, thus maintaining an acceptable degree of EMC. Electromagnetic susceptibility (EMS) is the inability of electronic system or device to perform without degradation in the presence of an electromagnetic distrubance. This definition focusses on susceptiility, which is a lack of immunity against internal or external interference. Design goals for EMS should emphasize the need for electronic equpment to be as robust as possible, not affected by radiated or conducted interference from other instruments. Modern technology is characterized by increase in system complexity, density of integration inside an electronic chip, and clock speeds in digital circuits. More electronic products incorporate intelligence through the use of microprocessors, which makes them both a source of interface and victims of external interference.

Professionals who develop, engineer, and manufacture electrical products should work together to provide integrated solutions to the problems that arise because of EMI. Ideally, electronic systems should be designed so that the level of radiated or conducted interference is very small, almost imperceptible. Additionally, the design should ensure that system functions are not affected in the presence of external electromagnetic fields or other interference that can find a path to the interior of the product through power lines. Various standards and regulations provide guidelines that define acceptable levels of interface that equipment can generated as well as the minimum external interference that the equipment has to tolerated while working and keeping its functional integrity.

The conference will cover the following areas:
EMI Sources, EMI Receptors, EMI Environment, EMI Specifications, EMI Standards, EMI Limits, EMI Measurement, EMI Control Techniques, EMC Design, EMS Measurement

The subject of electronics science and technology was part of the Deparment of Physics. A variety of instruments and systems were built and operated in the Department of Physics for science research in acoustics / ultrasonics, spectroscopy, solid-state physics, ionosphere and atmospheric physics. As the technology is progressing at an unassuming speed, the science instrumentation has grown to such an extent that it acquired a status of its own in form of a separate discipline. The new Department can be considered as an off-shoot of the Department of Physics. The Department of Systems Design was started in the year 2008. It is presently offering three new three-year duration courses at PG level and offering research pprograms in the areas of signal processing and instrumentation.
