Enhancing the Accuracy of Full-body Scanners for Improved Airport Security

If you’ve traveled by plane in recent years, you know the airport security drill: Put all your possessions through the X-ray detector, empty your pockets and step into one of the full-body scanners — or millimeter-wave holographic scanner, to use its official name. After you raise your hands above your head, the scanner sends out millimeter waves (mm-waves) that penetrate your clothing and bounce off your skin — or any other object you might be trying to conceal under your clothing, like a weapon of some sort. (The mm-wave radiation is 10,000 times less powerful than a single cellphone call, so you need not be concerned about any health effects.) An antenna array in the sweeping scanner device detects the reflected mm-waves and reconstructs an image of your body.

Antenna-to-Environment Interaction Insights with Visual Ray Tracing

When preparing for a business or personal trip, most of us want to check our travel routes in advance. There are many route-planning tools on the web today, and they help us to anticipate route difficulties such as heavy traffic, changes in street names, road sizes, accident locations, and many more. Some of these map applications even tell us what time we need to leave our starting location to reach our destination on time. Many of us end up “virtually” driving the route several times before we take the actual drive. Those virtual drives help us get from point A to point B in the shortest time possible, without unpleasant surprises.

Antenna system developers often face a similar challenge: We may have a great antenna design to get an RF signal from point A to point B in isolation, but the scattering environment around the antenna directly impacts the antenna’s ability to get the job done. So how do we anticipate the different routes that the signal might be forced to take to reach its destination? You guessed it—modeling and simulation of the antenna’s interaction with that environment. Continue reading
