We demonstrate micromachined reconfigurable metamaterials working at multiple frequencies simultaneously in the terahertz range. The proposed metamaterial structures can be structurally reconfigured ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

Electrical Properties Tomography (EPT) harnesses the capabilities of magnetic resonance imaging to reconstruct spatial maps of tissue conductivity and permittivity. This noninvasive technique ...

Fig. 1. The dielectric response models for conventional dielectric materials and for metamaterials. For conventional dielectric materials, there are three types of polarization models: Drude model for ...

Note: This article was originally published September 23rd, 2005 but we felt it was time for a little update based on some of the new products that surfaced to allegedly fix a non-existant problem.

A team of scientists in Australia claim to have stumbled on a breakthrough discovery that will have "major implications" for the future of quantum computing. Describing the find as a "happy accident," ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
