ELECTRICAL & ELECTRONICS ENGINEERING: Electrical engineering is concerned with the basic forms of energy that run our world. Whether it’s gas, hydro, turbine, fuel cell, solar, geothermal, or wind energy, electrical engineers deal with distributing these energies from their sources to our homes, factories, offices, hospitals, and schools. Electrical engineering also involves the exciting field of electronics and information technology. Wireless communication and the Internet are just a few areas electrical engineering has helped flourish, by developing better phones, more powerful computers, and high-speed modems. As we enter the 21st century, the technology that surrounds us will continue to expand and electrical engineers are leading the way. Electronics is the technology associated with electronic circuits and systems, and is one of the major branches of electrical engineering. It is a discipline that uses scientific knowledge of the behaviour and effects of electrons to create components, devices, systems or equipment that use electricity as part of their source of power. These components include capacitors, diodes, resistors and transistors.
Some of the specializations of Electrical and Electronic Engineering are:
1. VLSI & EMBEDDED SYSTEMS: The VLSI and Embedded Systems covers the fundamentals and engineering aspect of designing and developing IC based systems. Traditionally VLSI technology has emerged out as a successful conglomeration of two streams: material science and electrical engineering. The state of the art VLSI technology requires research in physical devices as well as novel design and development of electrical circuit. It focuses on developing hands-on skill of designing semiconductor devices and circuits, architecting systems using embedded components such as, CPU, memory and peripherals.
2. POWER SYSTEMS: The electric power industry is in the midst of exciting change. What was once a largely passive system is being redesigned to incorporate sensors, smart devices, advanced computer controls at many levels, and efficient handling of large amounts of electrical energy. Courses focus on modeling of different components of the system, design and operation of large interconnected power systems, fault analysis and protection, power electronics technologies for control of power devices, and renewable energy technologies. Students are exposed to smart grid concepts and various computer tools needed for analysis and design of efficient power systems. Students engaged in this option expect to work on challenging problems related to the delivery of large amounts of electrical energy in a safe, reliable, economical, clean, and sustainable manner.
3. DIGITAL SIGNAL PROCESSING: The world of science and engineering is filled with signals: images from remote space probes, voltages generated by the heart and brain, radar and sonar echoes, seismic vibrations, and countless other applications. Digital Signal Processing is the science of using computers to understand these types of data. This includes a wide variety of goals: filtering, speech recognition, image enhancement, data compression, neural networks, and much more. DSP is one of the most powerful technologies that will shape science and engineering in the twenty-first century.
4. TELECOMMUNICATIONS: Telecommunications is a universal term that is used for a vast range of information-transmitting technologies such as mobile phones, land lines, VoIP and broadcast networks. In telecommunications, data is transmitted in the form of electrical signals known as carrier waves, which are modulated into analog or digital signals for transmitting information. Analog modulation such as that used in radio broadcasting is an amplitude modulation. Digital modulation is just an updated form of this.
5. MICROELECTRONICS: This option focuses on digital hardware design with emphases on microprocessors and field programmable gate arrays. It is similar to the Embedded Systems option within the Computer Engineering program, but it focuses less on software and more on high-performance circuit design techniques.
6. REMOTE SENSING AND SPACE SYSTEMS: deals with Active (radar and lidar) and passive (radiometry) remote sensing of the atmosphere; radar, radiometer, and lidar systems; rocket and satellite instrumentation; atmospheric electrodynamics; meteoric effects in the ionosphere; modeling of atmospheric processes; plasma physics.
7. OPTICS: A technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
8. ELECTROMAGNETICS, NANOTECHNOLOGY & PHOTONICS: Whether naturally generated (i.e. solar radiation, lightning), or manmade (i.e. radio stations, cell phones, power lines), EM is all around us. Our offices, kitchens, and cars are all equipped with devices that rely on electromagnetic fields. EM comes into play every single time we turn a power switch on. The wireless communications revolution has EM at its very core. Voice and data information is transmitted and received via antennas. High frequency electronics, fiber optics, nanotechnology and almost every medical component on the market today require knowledge of electromagnetics.
9. WIRELESS COMMUNICATIONS: Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors. The transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication). Some of the devices used for wireless communication are cordless telephones, mobiles, GPS units, wireless computer parts, and satellite television.
