Microwave engineers usually mark their calendars for at least one key event each year: the IEEE's Microwave Theory & Techniques Symposium (MTT-S). Also known as the International Microwave Symposium (IMS), the high-frequency meeting is scheduled for June 8-13, 2003 in the Philadelphia Convention Center (Philadelphia, PA). As part of a full week of technical sessions, the event also includes a three-day Radio-Frequency Integrated Circuit (RF IC) Symposium (June 8-10) and a two-day Automatic RF Techniques Group (ARFTG) meeting (June 12-13) devoted to improved microwave measurement and calibration methods.

The theme of this year's event is "Liberty Through Microwaves." The IMS technical sessions run from June 10th through June 12th, with workshops and tutorial sessions scheduled for June 8th, 9th, and 13th. Tuesday's (June 10th) technical sessions include discussions onABUJA, June 4 (Reuters) - Nigeria's government has recovered $9.1 billion in stolen money and assets, its information and culture minister said on Saturday, as its corruption crackdown continues against the backdrop of the country's worst economic crisis in years.
