“…Then the radome is modeled by the PO method using J a , M a as the excitation, and the equivalent currents on the radome surface are determined. These two steps are the same as the decoupled antenna-radome analysis [1][2][3][4][5][6][7][8][9][10]; however the mutual interactions between the antenna and the radome are ignored. Two additional steps are implemented in the present hybrid analysis.…”

“…Firstly, the antenna is simulated as the radome is absent, and then the radome is modeled using the decoupled radiation fields from the antenna as the excitation. These analyses ignore the effects of the radome on the antenna [1][2][3][4][5][6][7][8][9][10]. In recent years, some researchers have taken the mutual interactions between the antenna and the radome into consideration [11][12][13][14][15][16].…”

Abstract-In this paper, the hybrid physical optics/boundary integral-finite element-mode matching (PO/BI-FE-MM) method is proposed for the analysis of the horn antenna enclosed by the electrically large radome. The radome is modeled by the PO method, and the BI-FE-MM method is implemented to the horn region. The equivalent PO currents on the radome surface are coupled into the BI-FE-MM equation of the horn region to account for the effects of the radome on the horn. With this hybrid method, the mutual interactions between the radome and the horn are fully considered. The radiation patterns, field distributions, and the S-parameters of the horns enclosed by different kinds of radome are presented.

“…One of the earliest methods to analyze the effect of the radome is the plane wave spectrum surface integration technique [1]. In that method, the aperture field distribution is considered as a bundle of rays which are traced through the radome wall.…”

Abstract-Nonconcentric reflector antenna-in-radome systems are used in applications especially requiring smaller radome coverages. The analysis of this two-dimensional geometry is performed for the Epolarization case. Here the geometry is decomposed into two parts and the analysis is performed by imposing the boundary conditions on each part as an iterative manner. This is known as the iterative boundary condition method in the literature. Convergence and accuracy are established numerically and it is seen that the expectations are really verified in reasonable CPU times. Also various numerical results are obtained for the description of the radiation characteristics.

“…So far, a variety of different approaches have been employed to investigate the modification of the radiation pattern of an antenna covered by a radome. These approaches can be divided into three categories: 1) high-frequency (HF) methods such as the ray-tracing technique [1][2][3]; the plane wave spectrum-surface integral technique [4], the physical optics method (PO) and dielectric physical optics (DPO) technique [5]; 2) low-frequency (LF) methods such as the method of moments (MoM) [6,7]; the finite element method (FEM) [8], and the method of regularization (MOR) [9]; and 3) analytical methods such as the dyadic Greens function method and iterative interaction procedure [10,11] which provide more physical insight but are applicable to radomes of special shapes. An important assumption of high frequency methods is that the structures have smooth surfaces and electrically large radii of curvature.…”

Abstract-A fast technique based on the Poggio, Miller, Chang, Harrington and Wu (PMCHW) formulation and the precorrected-FFT method is presented for accurate and efficient analysis of electromagnetic transmission through dielectric radomes of arbitrary shape (including airborne radomes). The method of moments is applied to solve the integral equations in which the surfaces of the radomes are modeled using surface triangular patches and the integral equations are converted into a linear system in terms of the equivalent electric and magnetic surface currents. Next, the precorrected-FFT method, a fast approach associated with O(N 1.5 log N ) or less complexity, is used to eliminate the requirement of generating and storing the square impedance matrix and to speed up the matrix-vector product in each iteration of the iterative solution. Numerical results are presented to validate the implementation and illustrate the accuracy of the method.
