“…At present, there are many literatures on aperture coupling with metal cavity (Jedlicka, 2000; SIAH Eng Swee, 2003; Li Kai, 2013;Peng Qiang, 2013) and computer box is the common simulation object, while the optical drive and floppy disk drive are usually considered as complete cavity without holes (Chen Xiuqiao, 2004;Yao Jianming, 2005). This approach is not consistent with the reality.…”

The electromagnetic coupling characteristics of a computer box under the high-power microwave (HPM) which includes the narrow-band and ultra-wideband HPM are studied. The simulations of radiation field in the computer box show that the optical drive and floppy disk drive are main channels through which the high-power microwave penetrates. The cut-off frequency of this corresponding dielectric waveguide and resonant frequency of computer box are the frequencies on which the coupling field is enhanced. The induced current on the cable show that the peak current value decreases with the increasing frequency. At the same time, the damage effect experiments of the computer under high-power microwave are carried out and the thresholds of three effect levels are summarized. The experimental results and the simulation are verified to some extent.

“…In Azaro et al (2002), a circuit approach was proposed for electromagnetic field coupling through rectangular apertures backed by rectangular boxes. To address more complex structures, a hybrid method of moments (MoM)/finite element method (FEM) technique in Jedlicka et al (2000) and Castillo (2001, 2002) was implemented to determine electromagnetic coupling into cavities having thin wires, dielectric materials, and a metal block. In Yang and Volakis (2005) and Siah et al (2003), it was observed that even a single wire could significantly degrade shielding effectiveness at frequencies where the wire becomes resonant.…”

This article considers the susceptibility of enclosed printed circuit board structures subject to external electromagnetic fields using a simple and efficient analysis. The method employs the magnetic currents on the nonmetallic surface of the cavity enclosing the multi-layer printed circuit boards. By using magnetic currents, coupling from one layer of the cavity to the other is conducted. In this manner, a single cavity Green's function is needed, avoiding the time-consuming modeling of junctions and vertical interconnects associated with multi-layer Green's functions. To validate the proposed method, numerical results and parametric studies are presented.

DISTRIBUTION /AVAILABILITY STATEMENTApproved for public release; distribution unlimited. ABSTRACT CMwimurfl 200 words) 12 b. DISTRIBUTION CODEThree related technical areas associated with modeling of electromagnetic coupling into complex systems were examined. The first area was the development of hybrid numerical models for modeling shielded enclosures containing wires of arbitrary orientation and shape and the shield containing tortuous path apertures. The second area was the modeling of very large cavities using domain decomposition methods. The third and final area was the accurate modeling of transient electromagnetic phenomena using methods borrowed from computational fluid dynamics. With varying degrees of success, progress was made in each area in advancing the state-of-the art. This was especially true in the development of the hybrid numerical methods and modeling of transient electromagnetic phenomena. In addition, the effort resulted in several publications as well as the graduation of several students. n. SECURITY CLASSIFICATION OR REPORT UNCLASSIFIED18. SECURITY CLASS1FICA
