When Intel said last week that it plans to stop using gigahertz figures to market its microprocessors, analysts said it was about time. A chip's clock speed is almost irrelevant in determining the ...

One of the most frequently touted measures of processor performance is a given chip's speed in gigahertz. Processors with higher GHz ratings can, theoretically, do more in a given unit of time than ...

Phononic circuits are emerging devices that can manipulate sound waves (i.e., phonons) in ways that resemble how electronic circuits control the flow of electrons. Instead of relying on wires, ...

Advanced Micro Devices Inc. on Monday beat rival chipmaker Intel Corp. to the market with the first gigahertz processor, which could turbocharge everything from games to voice programs and video on ...

It was a relatively quiet product announcement for Apple Computer , but then again, a speed upgrade to an existing product line is relatively unexciting. Apple unveiled three new Power Mac machines ...

Lithium niobate (LN) powers a newly developed optical metasurface for shaping and guiding light waves. Leveraging the electro-optical effect of lithium niobate, the device applies different electric ...

Somewhere between the HF projects many of us have worked on, and the visible light spectrum lies the UHF, EHF, SHF, and THF. That’s Ultra, Extremely, Super, and Tremendously High Frequency for those ...
