Re-engineering Engineering

A recent New York Times articles took another look at the Olin College of Engineering: Re-engineering Engineering

The result is a school with no academic departments or tenure, and one that emphasizes entrepreneurship and humanities as well as technical education. Its method of instruction has more in common with a liberal arts college, where the focus is on learning how to learn, than with a standard engineering curriculum. “How can you possibly provide everything they need in their knapsack of education to sustain them in their 40-year career?” Miller asked. “I think those days are over. Learning the skill of how to learn is more important than trying to fill every possible cup of knowledge in every possible discipline.”

Though the school charges no tuition, room and board is about $12,000 a year, which is in line with the full cost of a year at some state universities. Olin has already garnered an impressive amount of attention in the college guides. A Kaplan/Newsweek “How to Get Into College” guide called Olin one of “the new Ivies.” The Princeton Review says Olin “may well be the most dynamic undergraduate institution in the country.”

Surface Antennas Conform to Any Shape

From the Electrical Engineering focused EEBeat Blog – Surface antennas conform to any shape:

Recently developed Holographic Artificial Impedance Surfaces–or Textured Impedance Surfaces, for short–are surface-coating materials from HRL Laboratories (Malibu, CA) that enable any object to become a Tx/Rx antenna. Constructed of thin sheets of dielectric with small metal patterns on them, the materials have a metal backing and can be applied to metal surfaces.

The pattern is generated using two techniques:
(1) An artificial impedance surface, i.e. a structure containing small printed metal patterns. Electromagnetic impedance can be changed by printing different patterns on the surface.
(2) A concept used in optical holography is used to determine how the surface should be patterned. Just as an optical hologram HRL Labscan be created to look like any object, the thin surface material can be printed in such a way as to produce nearly any radiation pattern, regardless of the shape of the object on which it is placed.

During design, HRL needs to know the shape of the object, desired frequency bandwidth, and radiation pattern. The company then generates a file from that information that is used to print the pattern on the surface.
