The Use of Kramers-Kronig Relations for Verification of Quality of Ferrite Magnetic Spectra
Electrical, Control and Communication Engineering, 2015 The complex initial permeability (CIP) as a function of frequency is one of the main properties of ferrites. This characteristic (CIP) is measured experimentally, therefore there can be found noisy, doubtful or incomplete parts of the spectrum.

Tunable Quasi‐Resonances in Polypyrrole Nanodisks
Advanced Optical Materials, EarlyView.Polaronic carrier absorption enables electrochemically switchable quasi‐resonances in conducting polymer nanoantennas. ABSTRACT Redox‐tunable conducting polymers have emerged as promising materials for dynamic plasmonics and metasurfaces. However, only a few conducting polymers with particularly high conductivities (>1000 S/cm) have been reported to ...

Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Advanced Science, EarlyView.A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and

Quantum dynamics of the damped harmonic oscillator
New Journal of Physics, 2012 The quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energy is usually dealt with by including a discrete set of additional harmonic
