Abstract: Distance determination by Electron Paramagnetic Resonance (EPR) based on measurements of the dipolar coupling are technically challenging for electron spin systems with broad spectra due to comparatively narrow microwave pulse excitation bandwidths. With Na4[{CuII(PyMTA)}-(stiff spacer)-{CuII(PyMTA)}]… read more here.

Abstract: We propose a high-speed, dynamic strain measurement with random access based on real-time Brillouin time-domain analysis of correlated gain measured with an oscilloscope. A frequency-swept probe obtains the Lorentzian-shaped correlated gain in a time domain.… read more here.

DOI: 10.1109/jlt.2017.2759190
Abstract: We propose a novel BOTDA that can measure a BFS change appearing on a time axis with a single-shot measurement by using a frequency-swept probe pulse. The proposed method employs a very simple laser control… read more here.

Abstract: An opto-electronic oscillator (OEO) scheme which operates at "chirp oscillation" mode and generates low-phase-noise, frequency-swept microwave is proposed and experimentally demonstrated. This frequency-swept OEO is achieved by embedding a rapidly frequency-scanning microwave filter in an… read more here.
