- Microwaves from silicon chips?
- X-rays are widely used for medical imaging and security, but they still are dangerous. Would it be possible to replace X-rays by an imaging technology based on microwave radiation? Until now, it was not feasible because portable devices were not powerful enough. Now, two U.S. scientists have found how to...

- Strive to be an old-style microwave oven
- One never hears the terms "simple" or "straightforward" in connection with IT project failures. Courtesy of Coding Horror, here's a visual demonstration showing how so-called improvements can turn wonderful simplicity into painful complexity. The old-style microwave oven uses a single, easy to understand, dial: ...

- NASA monitors lightning inside hurricanes
- According to a new study from NASA, it is possible to forecast a storm's intensity by monitoring the lightning strikes near a hurricane's eye. And it can be done weeks before the storm arrives with the help of 'highly-sensitive sensors located thousands of miles from the storm.' Today, the Pacific...

- Research and Development of an RFID Based Disaster-Relief System
- A portable system for assisting rescue personnel in disaster situations has been developed. The system consists of portable microwave terminals that function as message readers/writers/carriers and long-range, non-battery RFID tags that are ubiquitously placed along roadsides and function as information-storage units. Information such as location of refuges and the safety...

- Thinking About WiMax
- WiMax is the commercialization of the work being performed by the IEEE 802.16 Working Group. 802.16 began with the goal of standardizing fixed microwave systems - and this really returns to the very roots of wireless, going back at least 60 years. WiMax eliminates at least some of the potential...
