Navigate your way to the 2010 IEEE International Symposium on Electromagnetic Compatibility (EMC) in the beautiful Greater Ft. Lauderdale/Broward County Convention Center in Fort Lauderdale Florida on 25 to 30 July. The symposium is sponsored by the IEEE EMC Society, features 6 concurrent technical sessions on Tuesday, Wednesday and Thursday. An Exhibit hall with over 300 booths filled with latest products, equipment and services. Monday and Friday feature 4 concurrent workshops/tutorials. In additions there are over 50 collateral industry and profession meetings planed thorough out the week. Finally there a numerous formal and informal opportunity to network with old friend, meet new friends, experts, professional and industry representatives.
The Greater Fort Lauderdale / Broward County Convention Center is located at the northern end of the Port Everglades; a secured commercial shipping and cruise ship port, and overlooking the inland Waterway. The address is 1950 Eisenhower Boulevard, Fort Lauderdale, Florida 33316, Phone 954-765-5900. For attendees navigating to EMC2010 with your GPS, the coordinates are: 26° 05’ 55” N, 80° 07’ 22” W.
Electromagnetic Compatibility is what is achieved when there is no undesirable Electromagnetic Interference. There are many ways for EMI to be coupled into electrical and electronic systems and just as many ways to mitigate and eliminate the EMI. To address these extremes we turn to understand, development, and application of the latest technologies, education, systems integration, products, and services. These engineering area offer great potential with the prospect of early implementation and international utilization. The IEEE International Symposium on EMC is the premier venue for the presentation of the cutting edge of the state-of-the-art in these areas. The conference objective is to provide a comprehensive overview of the latest in EMC research, design, and development in order to furnish attendees EMC information that is applicable to their organizations.
Conference topic presentations will describe the science, design, applications and technology. They will include applications in areas such as:
• Intrasystem EMC
• Intersystem EMC
• Electromagnetic Interference
• Electromagnetic Environments
• Electromagnetic Pulse
• Grounding & Bonding
• Transient Suppression
• Spectrum Management
• RF Radiation Hazards
• Electro-static Discharge
• Emission Control
As has been the case at all EMC Society sponsored conferences over the past 51 years, the attendees will participate in a meeting format which encourages an atmosphere of collegial interchanges and interaction among participants from diverse disciplines around the world.
Who Should Attend
The IEEE International Symposium on EMC has something for everyone! The technical sessions are well suited for the experience EMC Design or Manager Engineer. Professional development is provided at the Global University for novice engineers to the technical area of EMC. Students participation is recognized with a special Student Paper Award. Companions, be they spouse, family, friends or youth have their own program that provides tours of the Greater Fort Lauderdale and Miami area. There is even a special free Junior Technical Program that introduces the fundamentals of EMC to the youth.
Conducted Electromagnetic Interference
From Wikipedia, the free encyclopedia
EMI- Electromagnetic Interference: EMI is unwanted effects in the electrical system due to electromagnetic radiation and electromagnetic conduction. Electromagnetic radiation and electromagnetic conduction are differentiated by the way an EM field propagates. Conducted EMI is caused by the physical contact of the conductors as opposed to radiated EMI which is caused by induction (without physical contact of the conductors). Electromagnetic disturbances in the EM field of a conductor will no longer be confined to the surface of the conductor and will radiate away from it. This persists in all conductors and mutual inductance between two radiated electromagnetic fields will result in EMI.
Due to this EMI, the electromagnetic field around the conductor is no longer evenly distributed and causes skin effect, proximity effect, hysteresis losses, transients, voltage drops, electromagnetic disturbances, EMP/HEMP, eddy current losses, harmonic distortion, and reduction in the permeability of the material.
EMI can be conductive and/ or radiative. Its behavior is dependent on the frequency of operation and cannot be controlled at higher frequencies. For lower frequencies, EMI is caused by conduction and, for higher frequencies, by radiation. For ex: Skin effect is due to the conductive EMI and proximity effect is due to the radiative EMI.
The worst part of a high frequency electromagnetic signal is that it makes every conductor an antenna, in the sense that they can generate and absorb electromagnetic fields. In the case of a PCB (printed circuit board), which consists of capacitors and semiconductor devices which are soldered to the bread board, the capacitors and soldering act like antennas, generating and absorbing electromagnetic fields. The chips on these boards are so close to each other that the chances of conducted and radiated EMI are significant. Bread boards are designed in such a way that the case of the board is connected to the ground and the radiated EMI is diverted to ground. Technological advancements have drastically reduced the size of chipboards and electronics; however, this means they are also much more sensitive to EMI.
The most common solution to EMI is electromagnetic shielding. However, EMI shielding is expensive and has negative consequences. Another method to reduce EMI is to twist wires; however many facilities have tens of thousands of feet of wire, so this is not practical.
A common example of radiated EMI is a cable TV wire and the TV. If you unhook the cable from the TV and place it in front of the plug, video can still be seen on the TV. This is due to electromagnetic signals capable of traveling through the air from cable to TV.
From Wikipedia, the free encyclopedia
Electromagnetic interference (or EMI, also called radio frequency interferenceor RFI) is a disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. The source may be any object, artificial or natural, that carries rapidly changing electrical currents, such as an electrical circuit, the Sun or the Northern Lights.
EMI can be intentionally used for radio jamming, as in some forms of electronic warfare, or can occur unintentionally, as a result of spurious emissions for example through intermodulation products, and the like. It frequently affects the reception ofAM radio in urban areas. It can also affect cell phone, FM radio and televisionreception, although to a lesser extent.
