“…The power flow at a detector position has random directions. In this process, an initial ps EMP is continuously stretching [112,113] in the metal chamber resulting in the ns-scale radiation. Figure 29(c) is further increased due to reverberation, which is responsible for more frequent oscillations and the decreasing envelopes in Figure 30(a).…”

This paper provides an up-to-date review of the problems related to the generation, detection and mitigation of strong electromagnetic pulses created in the interaction of high-power, high-energy laser pulses with different types of solid targets. It includes new experimental data obtained independently at several international laboratories. The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce. The major emphasis is put on the GHz frequency domain, which is the most damaging for electronics and may have important applications. The physics of electromagnetic emissions in other spectral domains, in particular THz and MHz, is also discussed. The theoretical models and numerical simulations are compared with the results of experimental measurements, with special attention to the methodology of measurements and complementary diagnostics. Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions, which may have promising applications.

“…This is necessary, e.g., during the calculation of the system response in time domain by the inverse Fourier transform, when one has to perform the integration in the complex plane by applying the residue theorem. In the paper [15], e.g., this small quantity is assigned a physical interpretation, e.g., small radiation losses through an aperture or small losses in the walls. In other words, this quantity is connected with quality factor of the resonator Q by = 2 / [16].…”

Propagation of current waves along randomly located multiconductor transmission lines inside a rectangular resonator is investigated. Two different line configurations are considered: parallel wires and perpendicular lines. The analytical solutions for both types of lines are obtained, using the method of symmetrical lines inside the resonator. Computer realization of this method allows it to obtain a fast solution. Therefore, it becomes possible to investigate statistical properties of induced currents. It could be shown that the mutual coupling of the currents in the wires is strong when the frequency is near resonances in the system "cavity and wires" and relatively small far from these resonances. Stochastization leads to a broadening of the resonance curves.

“…The m and p radiate into half-space from where the plane wave is incident. In front of the other side of perfectly electric conducting surface, mirrored dipoles m and p , oriented in the same direction as m and p, radiate into completely closed metallic enclosure, and the size of m and p is the same as that of m and p [22], as shown in Fig. 3.…”

Abstract-An analytical model based on the Bethe's theory of diffraction by small holes is presented to predict the shielding effectiveness (SE) of metallic rectangular enclosure with electrically large aperture under plane wave illumination over a wide frequency range (0 ∼ 3 GHz). In this model, the aperture is represented as electric and magnetic dipoles located at the center of the aperture, and the coupling relation between external plane wave and electromagnetic field inside the enclosure is established. The approximate solution of electromagnetic field distribution inside the enclosure is obtained in terms of the integrals of the electric and magnetic dynamic Green function. Finally, the influence of enclosure thickness on SE is calculated by introducing thickness attenuation coefficient. The model considers the effect of the thickness on the calculation results and is simple with low computation complex and high estimation accuracy. Besides, the effects of parameters like enclosure and aperture dimensions, aperture and observation point positions, incident and polarization direction of the plane wave on SE can be analyzed comprehensively based on the model. Simulation results of the proposed model are in accord with that of the TLM method, which verifies the accuracy and reliability of the model.
