Electrical excitation and detection of magnetic dynamics with impedance matching [PDF]
Applied Physics Letters, 2012 Motivated by the prospects of increased measurement bandwidth, improved signal to noise ratio, and access to the full complex magnetic susceptibility we develop a technique to extract microwave voltages from our high resistance (∼10kΩ) (Ga,Mn)As microbars. We drive magnetization precession with microwave frequency current, using a mechanism that relies

Developments of a Novel Impedance Matching Circuit for Electrically Small Antennas [PDF]
Journal of Physics: Conference Series, 2006 In order to reduce the size of a wireless system, we have proposed the design formulas for an electrically small antenna (ESA), i.e. an antenna whose dimension is much smaller than a wavelength, with a miniaturized matching circuit which connects to a 50 ohm external circuit.

ASAIO Journal, 2023 Single lung transplantation (LUTX) can be the last therapeutic option for a growing cohort of patients suffering from end-stage respiratory failure. Postoperative ventilatory management of single LUTX recipients is challenged by the coexistence of the diseased native lung and a healthy—but fragile—graft.
