This paper describes a novel experiment on nitroxide radical spin labels using a multiarm EPR W-band bridge with a loop-gap resonator (LGR). We demonstrate EPR spectroscopy of spin labels by linear sweep of the microwave frequency across the spectrum. The high bandwidth of the LGR, about 1 GHz between 3 dB points of the microwave resonance, makes this new experiment possible. A frequency-tunabl...

The basic problem which this paper addresses is the following: given an arbitrary three-dimensional object, which moves along an arbitrary path (possibly rotating as it does so), to compute the volume swept out by the solid object as it moves, or in other words, to find the new solid volume which represents all of the points in space which the object has occupied at some time during the motion....

Lasers are often used to characterize samples in a non-destructive manner and retrieve sensing information transduced changes amplitude phase. In swept wavelength interferometry, wavelength-tunable laser is measure the complex response (i.e. phase) of an optical sample. This technique leverages continuous advances rapidly tunable lasers widely for sensing, bioimaging testing photonic integrated...
