My Note: Recently, I reached out to Dr. Willie Padilla, at Boston College regarding the amazing work he is doing at BC relating to the development of metamaterials which can be employed in the terahertz regime. Dr. Padilla along with his research assistants, graduate students, Claire M. Watts, and David Shrekenhamer, recently announced that they had created a revolutionary single-pixel imaging technique which takes images that are guided through a coded aperture using a semiconductor to guide and direct the reproduced image of an object once THz waves have passed through it. The BC team described this technique as depicted in the picture above in the following way:
"A new method for single pixel terahertz (THz) imaging developed by Boston College researchers uses a set of instructions delivered by a laser beam to tune THz waves in order to produce new types of THz images. During the imaging method devised by the team, THz waves pass through an object (a); then they strike a silicon semiconductor (b) given specific instructions about how to sample the image; that data is passed along in order to digitally reconstruct an image (c) of the original object in just a few seconds.

Here is what I wrote to Dr. Padilla, and his response, which Ms Watts,
