“…We will do more work on the radome analysis techniques to predict a radome-enclosed antenna's performance, such as the geometric optics (GO) and physical optics (PO) methods, in which the non-normal incidence and polarization effects should be considered [35][36][37]. Experimental measurements to confirm accuracy of homogeneous approximation of synthesized radome material are another interest of our further research [38,39].…”

Abstract-In this paper, electromagnetic optimal design is carried out for dual-band radome wall with alternating layers of staggered composite and Kagome lattice structure. The novel wall structure provides broadband transmission capability, along with excellent thermal-elastic properties and mechanical performances for high temperature applications. By optimizing the layer number (n) and the thickness of the whole wall (d), the power transmission efficiency of the novel structure in the frequency range of 1-100 GHz is calculated via boundary value method (BVM) based on electromagnetic theory. The calculation results suggest that if the wall thickness is dimensioned to be 6 mm and the wall structure is designed as 5 layers, the novel structure demonstrates excellent transmission performance. The optimal design results show that the power transmission efficiency is higher than 80% from 1 to 31 GHz in the centimeter wave range and from 59 to 100 GHz in the millimeter wave range, and the average transmission efficiency over the pass band reaches as high as 91%.

“…Method of moments (MoM) has also been used [5][6][7], possibly accelerated via a fast multipole method [8], as well as finite element method (FEM) [9]. More recently hybrid techniques mixing PO and MoM for low curvature parts and full-wave MoM method for the high curvature parts [10][11][12], or mixing PO, boundary integrals, mode matching and FEM [13] were investigated.…”

Abstract-State-of-the-art radomes exploit frequency selective media so as to be transparent for the frequencies of the antenna protected by them and opaque to other frequencies. This feature helps in reducing the radar cross section of the antenna and in protecting it from interference. The study of a frequency selective radome is a daunting task, since the radome is usually large in terms of wavelengths, hence full wave analyses are prohibitive. In this paper an approximate technique, based on the physical optics concept, is proposed to attain an estimation of the behavior of a radome shielded antenna in a short time with a commonly available computer. Results are validated against a full wave technique over a relatively small radome.

“…There are many methods for solving this kind of problems, such as the high frequency asymptotic methods, full-wave numerical methods and the hybrid full-wave and high frequency methods [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Full-wave numerical methods have been well developed to analyze the slotted-waveguide antenna [5][6][7][8][9].…”

“…However, due to large computation resources required, they usually are applied to analyze radiation by electrically small radome/antenna problems. For the scattering or radiation analysis of electrically large three-dimensional problems in electromagnetic engineering, the high frequency method is usually employed to achieve efficient calculation, such as Ray Tracing (RT), Physical Optics (PO), hybrid full-wave and high frequency methods [10][11][12][13][14]. But when these methods are applied to compute the radiation by a large antenna array with radome on a large aircraft, they usually become inefficient due to multi-scale, multi-regional connectivity and multi-materials problems.…”

Abstract-An accurate and efficient computational approach is presented for analyzing radiation characteristics of large antenna arrays with radome. This approach is based on the hybrid finite elementboundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA). Unlike the conventional singledomain FE-BI-MLFMA, the whole domain of the antenna array with radome is separated into many disconnected domains. A large free space area unavoidable in the single-domain FE-BI-MLFMA is eliminated in this multi-domain FE-BI-MLFMA formulation, thus the number of unknowns is greatly reduced in the presented multi-domain FE-BI-MLFMA approach. Different from the single-domain FE-BI-MLFMA, many integral equations are required in this multi-domain FE-BI-MLFMA. The numerical experiment shows that the presented multi-domain FE-BI-MLFMA is more efficient than the singledomain one while maintaining the same accuracy. A whole complicated system of a slotted-waveguide array with radome mounted on an aircraft is analyzed to further demonstrate the generality and capability of the presented multi-domain FE-BI-MLFMA.
