Lack of magnetoacoustic emission in iron with 6.5% silicon
PublikacjaZjawisko emisji magnetoakustycznej (EMA) na ogół tłumaczy się dwoma przyczynami: ruchem nie 180-cio stopniowych granic domenowych (1) lub kreacją i anihilacją domen magnetycznych. Artykuł prezentuje silne dowody na poparcie faktu, że to właśnie ruch granic nie 180-cio stopniowych odpowiada za powstawanie efektu EMA. Wynika to z wyników pomiarów dających zerowe natężenie efektu EMA przeprowadzonych dla szerokiego zakresu naprężeń...

A Subspace-Splitting Moment-Matching Model-Order Reduction Technique for Fast Wideband FEM Simulations of Microwave Structures
PublikacjaThis article describes a novel model-order reduction (MOR) approach for efficient wide frequency band finite-element method (FEM) simulations of microwave components.
