Colossal tunability in high frequency magnetoelectric voltage tunable inductors [PDF]
Nature Communications, 2018 AbstractThe electrical modulation of magnetization through the magnetoelectric effect provides a great opportunity for developing a new generation of tunable electrical components. Magnetoelectric voltage tunable inductors (VTIs) are designed to maximize the electric field control of permeability.

Analysis of the coverage of tunable matching networks with three tunable elements [PDF]
2017 IEEE MTT-S International Microwave Symposium (IMS), 2017 Tunable matching networks are crucial for agile radio frequency circuits. To optimally design such networks the overall coverage needs to be determined. In this work, analytical formulas for the coverage area within the Smith chart of a three-element tunable-network are derived.

Use of diffuse reflections in tunable diode laser absorption spectroscopy: implications of laser speckle for gas absorption measurements [PDF]
, 2008 We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...
