Theory of light emission in sonoluminescence as thermal radiation.
Based on the model proposed by Hilgenfeldt [Nature (London) 398, 401 (1999)], we present here a comprehensive theory of thermal radiation in single-bubble sonoluminescence (SBSL). We first invoke the generalized Kirchhoff's law to obtain the thermal emissivity from the absorption cross section of a multilayered sphere (MLS). A sonoluminescing bubble, whose internal structure is determined from ...
متن کاملElectromagnetic Theory -
Magnetomotive force (mmf) Magnetomotive force is the flux producing ability of an electric current in a magnetic circuit. [It is something similar to electromotive force in an electric circuit]. [Unit of magnetomotive force is ampere (A)] Note: Although some books use the term ampere-turns, it is strictly not correct as turns is not a dimension] mmf I = Σ I Consider a coil having N turns as sho...

متن کاملElectromagnetic Modeling of Outcoupling Efficiency and Light Emission in Near- Infrared Quantum Dot Light Emitting De- Vices
We report an analytical exciton emission model based on Green function for simulating the radiation characteristics of nearinfrared Quantum Dot-light emitting devices (QD-LEDs). In this model the internally emitted light can be classified into the following modes: Substrate, indium tin oxide (ITO)/organic waveguided, surface plasmonic modes, and external emitted mode. We investigate the influen...
متن کاملTheory of Gas Ionization by Intense Electromagnetic Fields
The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...
