Application of the resonant rotating wave approximation to the theory of resonant scattering
A theoretical study of the resonant scattering of light, including the effects of strong fields, is reported. The formulation is developed within the context of a new approximation, the resonant rotating wave approximation (RRWA). The RRWA is similar to the standard R\-lA, except that non-resonant …

High-frequency off-line power conversion using quasi-resonant and multi-resonant techniques
… (ZCS) and zero-voltage-switching (ZVS) quasi-resonant techniques, and the zero-voltage-switching multi-resonant technique, are evaluated for high-frequency, off-line applications. The study is performed with emphasis on the conversion-frequency range, efficiency, load range, input-voltage …

Extended describing function method for small-signal modeling of resonant and multi-resonant converters
… for PWM topologies and various soft-switching resonant topologies. The proposed method is demonstrated using four resonant topologies and two multi-resonant topologies. These circuits are strongly oscillatory, and thus they cannot be modeled by means of traditional averaging techniques. By …

Resonant Forcing of Nonlinear Systems
We include the additional constraint that only select degrees of freedom be forced, corresponding to a very general class of problems in which not all of the degrees of freedom in an experimental system are accessible to forcing. We find that certain Lagrange multipliers take on a fundamental …

Study of resonant charge transfer
Experimental measurements ol N₂ resonant charge transfer cross sections were performed. It was found that the energy of electrons used to produce the N₂⁺ ions is an important variable with respect to cross section. An examination of the experimental precision was performed and it was found that the …

Constant-frequency resonant power processors
Two constant-frequency resonant power processors are discussed. The parallel resonant converter(PRC) with a controlled output rectifier can provide both forward and reverse power flow. A new control parameter — "θ-angle" is proposed for achieving output regulation and bidirectional power flow of …

Quasi-elastic resonant x-ray scattering
In the fast collision approximation, the scattering amplitude operator of the quasi-elastic scattering is expressed as the summation of multipole moment operators $M\sp{(k)}(l\sb{i},s\sb{i})$ of the valence shell involved in the resonance$\sp1$ with distinct polarization factors. Each multipole …
