Experimental Verifications and Simulations of Magnetic Motor of Circular Miniature Loudspeaker for Total Harmonic Distortion Improvement

, 2011
The reduction in total harmonic distortion of miniature loudspeaker is reported by investigating the force factor (Bl(x)). Micro tensile testing is employed to get Bl(x) vs x curves, which verify finite element simulation. Furthermore, magnetic system of

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

A three-phase current source inverter with third harmonic injection for grid-connected renewable power sources [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla"
A novel three-phase voltage-synchronized current source (VSCS) converter with third harmonic injection is proposed in this paper. Compared with the conventional vector current control (VCC), phaselocked loop (PLL) is completely removed in this method ...

Descriptors to Dynamics: A Materials and Device Perspective on in‐Materio Physical Reservoir Computing for Neuromorphic Edge Intelligence

Advanced Materials, EarlyView.
Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Reduction of the Higher Harmonic Distortion of the RC Oscillator [PDF]

A new method to reduce the harmonic distortion of the RC oscillator is presented. The output signal of the RC oscillator is delayed by π/ω and subtracted from the original signal so that the fundamental components are summed up and the second harmonic ...

Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon

Advanced Materials, EarlyView.
We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...
