The streamlined shapes of airborne radomes tend to cause severe degradation of the electromagnetic (EM) performance, which could be compensated by properly designing the thickness profile of the radome. Boresight error (BSE) and transmission loss (TL) are the two most important EM characteristics that need to be improved. Previous researches focused on the(More)
The analysis of the enclosure's shielding effectiveness (SE) is an important work in the electronic device's electromagnetic compatibility problem. Almost all devices cannot work without connected accessory including cables and electronic connectors. Except for apertures and seams on the enclosure, the connected accessory is also a leakage path for(More)
Modern radomes are commonly made of composites, whose material properties inevitably have errors due to the complicated manufacturing process, thus degrading the electromagnetic (EM) performance of radomes. In this letter, both systematic and random material properties errors are introduced in the EM analysis of radomes. A statistical method is proposed,(More)
Since the curved surface of a cable-network reflector is generally approximated by regular flat facets, the electromagnetic performance of the cable-network reflector is determined by the size and shape of the facets. In many cases, the geometric approximation errors of the facets are periodically distributed on the surface, which can result in strong(More)
The presence of radome inevitably degrades the electromagnetic (EM) performance of the enclosed antenna while the deformation of the radome may make the degradations even worse. This letter studies the effect of structural deformation of a metal space frame (MSF) radome on EM performance. Far field of the antenna-radome system is obtained by adding the far(More)
Inhomogeneous radomes, characterized by stacked layers of continuously varying dielectric parameters, are potential in yielding excellent electromagnetic (EM) performance. This two-part sequence of papers presents a study on the EM performance of inhomogeneous airborne radomes based on impedance match, including comparison with the conventional constant(More)
As the geometry thickness error of composite radome impacts the electromagnetic (EM) performance of the antenna-radome system, a novel interval arithmetic analytic approach to the analysis of the effect on average power pattern of antenna-radome system with the thickness error in the composite radome-based is proposed. The thickness error of radome’s(More)
In the first part of a two-paper sequence, the phase distortion caused by inhomogeneous radomes is studied to reveal the boresight error (BSE) characteristics, and a method is proposed to estimate the insertion phase delay distribution and the BSE. In this second part, the bandwidth performance and the effect of radome coating, thickness errors, and layer(More)
For the problem that the material property error of composite radome will impact the electromagnetic (EM) performance of the antenna-radome system, a novel analytic approach for the research of the effect on average power pattern of the antenna-radome system with the material property error (including permittivity and loss tangent) in the composite radome(More)
In this communication, a new Taylor expansion-based interval pattern analysis method is developed to predict the impact of the small excitation amplitude uncertainty on the radiated array pattern. The dependence problem of the classical interval arithmetic, which may lead to overestimation of performance intervals, is addressed in this communication. The(More)
