A duo of electrical engineers (or mad scientists, if you prefer) at the California Institute of Technology have developed chips that could very well end up in the next James Bond movie. Or, you know, real life. The newfangled chips are capable of generating and radiating "high-frequency electromagnetic waves, called terahertz (THz) waves, that fall into a largely untapped region of the electromagnetic spectrum." They can penetrate a host of materials without the ionizing damage of X-rays, and apparently, can be integrated into small, handheld devices. The university is already dreaming of potential applications -- everything from homeland security to wireless communications to health care, and even touchless gaming. In theory, this kind of work would eventually lead to noninvasive cancer diagnosis as well. The technobabble can be seen in full at the source link.
