The shielding problem of a planar conductive screen exposed to a vertical electric dipole with a delta-type pulsed current is analytically solved in the time domain. The approximate solutions for both the longitudinal and transverse components of the shielded electric field are derived throughout the shielded space using the inverse Laplace transform method. These solutions are applicable when the diffusion time is much longer than the transit time and the distance from an observation point to the source is much larger than the screen thickness. A finite-duration pulse can be approximated as a delta-type pulse if its duration is much shorter than the diffusion time and its dominant frequencies fall within the feasible range.

High-altitude electromagnetic pulse (HEMP) poses a serious threat to critical equipment in power systems. Existing standard conducted environments, due to neglecting the transient response characteristics of actual lines, are difficult to accurately guide the effect testing and survivability assessment of power equipment. To address this issue, this article systematically investigates the transient conducted environment characteristics of transmission and distribution lines under HEMP by constructing a comprehensive simulation model that includes insulator flashover, surge arrester operation, and the broadband equivalent circuit of distribution transformers, combined with the finite difference-time domain (FDTD) field-line coupling algorithm and the Simulink simulation platform. The results show that: insulator flashover significantly limits the amplitude of conducted voltage, but retains the nanosecond-level rising edge characteristics; surge arresters cause waveform overshoot due to parasitic parameters; the waveform parameters of the distribution transformer port voltage are influenced by factors such as the angle of incidence and ground conductivity, with typical characteristics being a double exponential pulse with a rise time of 20 ns, a half-width of 500 ns, and a peak value of 440 kV; the conducted environment model established based on the actual transient response of the lines can provide input conditions that are closer to engineering scenarios for vulnerability assessment tests of power equipment. The research results overcome the scenario limitations of traditional standard conducted environments and provide theoretical support and a data foundation for HEMP effect threshold extraction and protection design of power systems.

In this letter, a miniaturized single-layer dual-polarized energy selective surface (ESS) is proposed with each element size of 0.15 λ0 × 0.15 λ0. The method of equivalent circuit model is applied to analyze operation principle of the proposed ESS, showing that a transmission pole and zero are generated when the diodes are in OFF- and ON-state, respectively. As a result, low insertion loss (IL) and high shielding effectiveness (SE) can be obtained. The calculated and simulated results verify that the proposed design can transmit low-power communication signals in the range of 2.47–3.5 GHz with the IL less than 1 dB, while achieving more than 10 dB SE against high-power microwave (HPM) incidence across 1.85–4.32 GHz. The nonlinear characteristics of the proposed ESS can be conducted in the field-circuit co-simulation and demonstrated in the rectangular waveguide. Due to the self-actuated response, the proposed ESS possesses the ability of adaptive protection against HPM attacks.
