Electromagnetics, Remote Sensing and Microwaves

In this curriculum area, students learn the fundamental concepts and 
applications of electromagnetics fields and their use in 
device, communications, and sensing applications.

Electromagnetics is the fundamental physics of electrical engineering, and 
describes how electric charges and currents create electric and magnetic 
fields. These fields give rise to the concepts of resistance,
inductance, and capacitance that are fundamental to circuit theory.
Electromagnetic fields further create the propagating waves that
enable broadcast, cellular, and satellite communications in the
radiowave, microwave, and millimeter wave portions of the electromagnetic
spectrum. These waves can also be used for sensing the world around us by
creating radar and microwave radiometer systems. Such sensors have the
ability to penetrate clouds and rain, and are not dependent on solar
illumination, so that they are widely used for long range measurements
of the surrounding environment.

Ohio State is a leader nationwide in the development of new electromagnetic,
remote sensing, and microwave technologies. The ElectroScience Laboratory
on West Campus is a unique department asset providing outstanding
research facilities for this area. Research projects in the laboratory
include the design of new antennas and sensors, the development of
electromagnetic computer simulation and modeling tools, the
creation of new radar and navigation technologies, the analysis of 
datasets from Earth observing satellites, and a host of other areas.

Career opportunities for experts in the area are outstanding, as the area
is in high demand with a limited number of experts nationwide. The growing
importance of enhanced microwave technologies for data networks has 
motivated new positions in the communications industry, including 
companies such as Intel, Qualcomm, Apple, and others. Expertise in this 
area is also in high demand for defense applications.
