The backward wave oscillator (BWO) is an important vacuum electron source that utilizes backward waves to interact with electron beam, resulting in high-frequency self-excited oscillations. Due to the ...

We present the first scanning tunneling microscopy (STM) image of hydrogenic acceptor wave functions in silicon. These acceptor states appear as square-ring-like features in STM images and originate ...

PIC simulations of an X-band Relativistic Backward-Wave Oscillator (BWO) driven by the high-current, high-voltage SI-NUS-6 accelerator are performed using the CST-PS particle-in-cell (PIC) code. A ...

There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, outgoing light wave. In particular, the time delay of the transition from ...

Sophie Turner shares a humorous yet shocking story on Late Night with Seth Meyers about how a harmless wave at Comic-Con led to an A-list couple's breakup. Discover the unexpected drama behind her ...

Seasonable warmth will give way to another taste of fall and chance of rain later this week.

First, they used errors from the standard signal-fitting process, based on a simple harmonic oscillator model of the tip surface contact, to detect which data points were unreliable.
