We propose an efficient method for calculating the electromagnetic field of a large-scale array optical nanoresonators based on coupling theory quasinormal mode (QNM). In this method, two approaches scattered-field reconstruction and stationary-phase-principle calculated plane-wave expansion are developed to obtain regularized QNM (RQNM) in different regions. This accurate calculation RQNM resolves far-field divergence issue QNMs QNM-coupling theory, thus enabling rapid computation...
We propose an efficient method for simulating the motion of multiple nanoparticles under light-field excitation. By exploiting a recently reported based on coupling theory quasinormal mode (QNM) electrodynamics (ED) calculation optical force, this can achieve fast Langevin dynamics (LD) simulation nanoparticles, which incorporates not only routinely considered viscous resistance and Brownian but also electrostatic double-layer force between particles. Compared to ED-LD methods that rely...
A 30 MeV compact cyclotron used for medical radioactive isotope production is in construction. program controlled mapping instrument with accuracy 10/sup -4/ was developed. Its probe moves automatically the mm gap covering a circular area more than 1600 diameter. It makes efficient and accurate. An iteration method both harmonic average field shimming. The results were so good that first reduced from 10 gauss to about 5 most of radius 70 central region. Meanwhile total phase shift which...
Electromagnetically induced transparency (EIT) is a significant nonlinear optical phenomenon. Based on the theory of density matrix equation, we presented influence Doppler effect EIT. A cascade type three-level system and Na atomic vapor adopted during course. The results showed that EIT determined by Rabi frequency couple probing field. It independent temperature usually. But when take into account, it found full appeared at condition Ω<sub>P</sub>=0.01GHz, Ω<sub>C</sub>=1GHz...
The coupling between fluorescent emitters and the metal nanowire (NW) can excite guided surface plasmon polaritons (SPPs) on NW be exploited to extract characteristic parameters of emitters.
