High sensitivity and broad bandwidth magneto-impedance effect in magnetic microstrip lines

, 1997
A unique magneto-impedance effect by directly flowing microwave power in a Magnetic Microstrip Line was investigated. The microwave can be modulated by external fields that caused the impedance change due to the permeability variation in the magnetic ...

Broadband parametric amplification with impedance engineering: Beyond the gain-bandwidth product

, 2015
We present an impedance engineered Josephson parametric amplifier capable of providing bandwidth beyond the traditional gain-bandwidth product. We achieve this by introducing a positive linear slope in the imaginary component of the input impedance seen ...

Harmonic resonance analysis in PMSG based wind farms: comparison of simplified and detailed impedance models and passive and active damping

Scientific Reports
To study harmonic resonance in power grids with wind farms, often impedance models are used that in some cases include the converters’ control systems. However, a key question is whether a wind power plant (WPP) simplified impedance model, ignoring the ...
