“…Oscillating systems of higher order as well as spatially extended systems have a large (infinite) number of eigenfrequencies. Closely spaced natural frequencies can lead to beating effects in the response functions (see, e.g., [19]). Thus, the cavity is represented as a set of oscillators which are driven by an exterior force (electrical field).…”

In this paper, analytical solutions of response functions for rectangular resonators are investigated in time domain. Emphasis is placed on the study of electromagnetic field coupling to a 3-D cavity through a small circular aperture. The time-dependent parts of the resulting modal Green's functions exhibit typical behavior that is inherent in all resonating/oscillating linear physical systems: namely, they fulfill oscillating ordinary differential equations at any point of the considered resonator. Their solutions contain transient and steady-state parts. The transient parts of the response functions will become important for electromagnetic compatibility tests in particular of modern digital high-speed electronics.

“…The set of Pocklington integrodifferential equations (11) has been solved by using the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). An outline of the method is given here, for the sake of completeness while the method has been presented in detail elsewhere, for example, in [8].…”

“…The electromagnetic field coupling to overhead wires is of great practical interest for many EMC applications [1][2][3][4][5][6][7][8][9][10][11], such as transient excitation of antennas, power, or communications cables. The electromagnetic field coupling to finite length overhead wires can be determined by means of the transmission line model or the thin wire antenna theory in either frequency or time domain [1].…”

The paper deals with two different approaches for the analysis of electromagnetic field coupling to finite length overhead wire: the wire antenna theory (AT) and the transmission line (TL) method. The analysis is carried out in the frequency and time domain, respectively. Within the frequency domain analysis the wire antenna formulation deals with the corresponding set of Pocklington integrodifferential equation, while the transmission line model uses the telegrapher's equations. The set of Pocklington equations is solved via the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM), while the telegrapher’s equations are treated using the chain matrix method and the modal equation to derive per-unit-length parameters. For the case of the time domain analysis AT model uses the space-time Hallen integral equation set, while TL approach deals with the time domain version of the telegrapher’s equations. Hallen equations are handled via time domain version of GB-IBEM, while time domain telegrapher’s equations are solved by using Finite Difference Time Domain (FDTD) method. Many illustrative computational examples for the frequency and time domain response, respectively, for several configurations of overhead wires, obtained via different approaches, are given in this paper.

“…where subscript 0 and L is related to the distance from the observation point to the source point located on the real and image wire, respectively. The ground effects are included in the formulation through the space-time dependent reflection coefficient for TM-polarization, [6] which, for convenience, can be written in the form:…”

“…The GB-IBEM solution of Pocklington equation in free space for certain values of time domain integration parameters has been presented in [5], while the Hallen equation solution via GB-IBEM have been obtained for thin wire configurations in the presence of a dielectric half-space, e.g. in [6]. The original formulation has been developed for a single wire located horizontally above [2] and a below real ground, respectively [7].…”

The paper deals with the space-time Galerkin-Bubnov scheme of the Indirect Boundary Element Method for the solution of time domain integral equations for thin wires in the presence of lossy media of the Pocklington and Hallen type, respectively. The presence of a dissipative half-space is taken into account via the corresponding space-time reflection coefficients. Some illustrative computational examples related to the overhead wires and grounding electrodes are presented.
