This paper proposes an approach to the computer simulation of electromagnetic, thermal and mechanical fields in ferromagnetic bodies based on the developed mathematical model for the description of thermo-mechanical processes in electroconductive bodies having different magnetizability and polarizability under electric field conditions. The results of the investigation on the modes of high-temperature...
With both analytical and numerical methods, chaotic motions of a clamped thin circular elastic plate in coupling fields are investigated in this paper. The chaotic motions arising from the transverse intersections of the stable and unstable manifolds of the heteroclinic orbits are analyzed by means of Melnikov method. The critical curves separating the chaotic and non-chaotic regions are obtained...
LOD-FDTD numerical method was introduced and the computation model of rectangular cavity with slot was established and the coupling field of the electromagnetic pulse into cavity with slot on it was studied by LOD-FDTD numerical method. The study showed that cavity and slot resonance field became a secondary radioactive source successively that transmitted electromagnetic energy to outer space in...
we present a theoretical study on a four-level atom system with a triplet ground state and an exicited state driven by two coupling fields, a rf field and a probe field. The absorption spectrum is characterized by two EIT. It can be found that the linewidth of the two EIT change with the relative phase of the two coupling fields. The linewidth reaches the minimum when the relative phase is equal to...
Summary form only given. We study interference between electromagnetically induced transparency (EIT) features in the radio frequency region of the spectrum associated with an electron spin resonance in the nitrogen-vacancy center in diamond. Measurements are made using a coherent optical detection technique. Two EIT features can be induced in a single absorption band by two coupling fields at different...
