The problem of excitation of electromagnetic fields by a material body of finite dimensions in presence of coupling hole between two arbitrary electrodynamic volumes is formulated. The problem is reduced to two-dimensional integral equations for the surface electric current on a material body and the equivalent magnetic current on a coupling hole. A physically correct transition from the initia...

2 The aim of this paper is to present a way of ranking the nonlin3 earities of electrodynamic loudspeakers. For this purpose, we have 4 constructed a nonlinear analytic model which takes into account the 5 variations of the small signal parameters. The determination of these 6 variations is based on a very precise measurement of the electrical 7 impedance of the electrodynamic loudspeaker. Firs...

We investigate numerically the architecture dependence of the characteristics of antibunched photons generated in cavity quantum electrodynamic systems. We show that the quality of antibunching [the smallness of the second-order intensity correlation function at zero time g(2)(0)] and the generation efficiency significantly depend on the configurations: the arrangements of single-mode optical c...

We set up the Maxwell's equations and subsequently the classical wave equations for the electromagnetic waves which together with the generating source, a traveling oscillatory charge of zero rest mass, comprise a particle traveling in the force field of an usual conservative potential and an additional frictional force f ; these further lead to a classical wave equation for the total wave of t...

Electrodynamic shakers are widely used in experimental investigations of vibrated fluids and granular materials. However, they are plagued by undesirable internal resonances that can significantly impact the quality of vibration. In this work, we measure the performance of a typical shaker and characterize the influence that a payload has on its developed by Goldman (2002) [1] which consists of...

The performance of more than 60 different electromagnetic energy harvesters described in more than 100 publications is benchmarked. The benchmarking is based on earlier published parameters from literature as well as on two novel parameters introduced in this paper. The former allow to compare different harvester conversion principles as well as harvesters of different electrodynamic design pri...
