متن کاملCasimir Energy for a Spherical Cavity in a Dielectric: Applications to Sonoluminescence
In the final few years of his life, Julian Schwinger proposed that the “dynamical Casimir effect” might provide the driving force behind the puzzling phenomenon of sonoluminescence. Motivated by that exciting suggestion, we have computed the static Casimir energy of a spherical cavity in an otherwise uniform material. As expected the result is divergent; yet a plausible finite answer is extract...
متن کاملradiative absorptivity calculations of a spherical cavity
this paper investigates the radiative absorptivity of a spherical cavity by using monte carlo techniques. several parameters such as the angle of incoming radiation which inters the cavity for both diffuse wall cavity and specular wall cavity has been investigated. the absorptivity of a spherical cavity has been calculated and compared with the exact values when the angle of incoming radiation...
متن کاملOKHEP-95-06 Casimir Energy for a Spherical Cavity in a Dielectric: Toward a Model for Sonoluminescence?
In the nal few years of his life, Julian Schwinger proposed that the \dynamical Casimir e ect" might provide the driving force behind the puzzling phenomenon of sonoluminescence. Motivated by that exciting suggestion, I have computed the static Casimir energy of a spherical cavity in an otherwise uniform material with dielectric constant and permeability . As expected the result is divergent; y...
متن کاملModelling of Surface Charge Decay in a Spherical Cavity within a Solid Dielectric Material Using Finite Element Analysis
The modelling of cavity surface charge decay through conduction along the cavity wall using the Finite Element Analysis (FEA) method is presented in this paper. A field-dependent cavity surface conductivity is proposed and the Phase-Resolved Partial Discharge (PRPD) patterns obtained from experimental measurements used to validate the simulation results generated using the model. A comparison b...
