New vacuum power amplifier demonstrated at 0.85 Terahertz
The submillimeter wave, or terahertz, part of the electromagnetic spectrum falls between the frequencies of 0.3 and 3 terahertz, between microwaves and infrared light. Historically, device physics has prevented ...
Tiny sensors put the squeeze on light
Microelectromechanical systems, known as MEMS, are ubiquitous in modern military systems such as gyroscopes for navigation, tiny microphones for lightweight radios, and medical biosensors for assessing the ...

New diamond and gold-based techniques let scientists measure and control the temperature inside living cells
How do you take the temperature of a cell? The familiar thermometer from a doctor's office is slightly too big considering the average human skin cell is only 30 millionths of a meter wide. But the capability ...
Novel hollow-core optical fiber to enable high-power military sensors
The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and dramatically ...
