Abstract-This paper presents a broadband switchable 3D structure, which can be used to protect the information equipment from high intensity microwave wave. Compared to other designs, the proposed structure in this paper has wider working band. When the amplitude of incident wave within working band is low, the structure will allow them to pass with little loss. As the amplitude of incident wave is high enough to activate diode, the wave will be reflected. The full-wave simulations are performed in CST to analyze the transmission performance. The simulated results verify the transmission performance and defending function. Its working principle is explained through change of the effective material parameters at two states. A prototype is fabricated. The protection property of the structure as a function of intensity of incident wave is verified in waveguide simulator.

“…the electromagnetic topology (EMT) (Baum, 1980) approach, the fault tree analysis (FTA) (Genender et al, 2011b) and Bayesian networks (BN) (Mao and Zhou, 2010;Mao et al, 2011). To calculate the risk with one of these three methods, it is necessary to acquire all the data for the calculation by many different measurements of its subsystems.…”

Abstract. This paper introduces a procedural method based on fuzzy logic to analyze systematic the risk of an electronic system in an intentional electromagnetic environment (IEME). The method analyzes the susceptibility of a complex electronic installation with respect to intentional electromagnetic interference (IEMI). It combines the advantages of well-known techniques as fault tree analysis (FTA), electromagnetic topology (EMT) and Bayesian networks (BN) and extends the techniques with an approach to handle uncertainty. This approach uses fuzzy sets, membership functions and fuzzy logic to handle the uncertainty with probability functions and linguistic terms. The linguistic terms add to the risk analysis the knowledge from experts of the investigated system or environment.
