Presentation Transcript

The study and application of electric and magnetic fields

Electrical Engineering is Applied Electromagnetics:

- - Circuit Theory
- - Kirchhoff’s Voltage and Current Laws
- - Current
- - Resistance
- - Capacitance
- - Inductance
- - Voltage
- Electric and Magnetic Energy
- Power, Electric Machines
- Antennas, Waves and Wave Propagation, Optics
- and Optical Computing

Electrical Engineering is Applied Electromagnetics

- As devices get smaller and smaller, and frequencies get higher and higher,
- circuit theory is less able to adequately describe the performance or to
- predict the operation of circuits.
- At very high frequencies, transmission line and guided wave theory must
- be used - high speed electronics, micro/nano electronics, integrated circuits.
- Other applications of Electromagnetics -
- Fiber Optics
- Microwave Communication Systems
- Antennas and wave propagation
- Optical Computing
- Electromagnetic Interference, Electromagnetic Compatibility
- Biology and Medicine/Medical Imaging

- As use of the electromagnetic frequency spectrum increases, the
- demand for engineers who have practical working knowledge
- in the area of electromagnetics continues to grow.

- Electromagnetic engineers design high frequency or optoelectronic
- circuits, antennas and waveguides; design electrical circuits that
- will function properly in the presence of external interference
- while not interfering with other equipment.

- The electromagnetics technical specialty prepares future engineers
- for employment in industry in the areas of radar, antennas, fiber
- optics, high frequency circuits, electromagnetic compatibility
- and microwave communication.
