Title:

Microstrip Array Antenna

Patent No:

5,818,391

Date:

10/06/1998

Inventor:

Choon Sae Lee
Department of Electrical Engineering, School of Engineering 

Description:

The subject invention produces a compact, flat, high-gain (beam-focusing) antenna based on revolutionary microstrip antenna technology. Power losses in the feeding structure are minimized through a novel feeding technique that does not require a transmission line to each element.

Title:

System and Method for Predicting the Behavior of a Component

Patent No:

6,064,810

Date:

05/16/2000

Inventors

Peter E. Raad, et al
Department of Mechanical Engineering, School of  Engineering

Description:

The invention describes a transient, multiple-grid solution system that leads to a dramatic decrease in computational time requirements for complex three-dimensional problems. The meshing technique is adaptive, is independent of initial grid size, and allows the user to specify accuracy requirements.
