What is Electromagnetics?
The study and application of electric and
magnetic fields
Electrical Engineering is Applied
Electromagnetics

• - Circuit Theory
• - Kirchhoffs 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

Why Electromagnetics?
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

Why Electromagnetics?

• 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.
