“…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%.

“…The power transmission efficiency of the graded panel sheet with the size of 100 × 100 mm is tested by free space transmission method in a dark microwave room, which is similar to the method in Refs. [28,29]. It consists of a network analyzer where the incident and transmission ports are connected to two horn antennas located on each side of the test panel.…”

Abstract-Silicon nitride (Si 3 N 4 ) ceramic is a promising ultra-high speed (> 5 mach) broadband (1-18 GHz) radome material because of its excellent high-temperature resistance, good mechanical and dielectric properties. Si 3 N 4 ceramics with A-sandwich wall structure are successfully applied to passive self-direction high transmission efficiency broadband radome (1-18 GHz). In the present study, a novel graded porous wall structure for broadband radome is promoted. The feasibility of using this structure is carried out by a computer aided design for the wall structure based on the microwave equivalent network method. By optimizing the layer number (n), structural coefficient (p), thickness (d) and dielectric constant (ε) of each layer, the power transmission efficiency at 1-18 GHz of graded porous Si 3 N 4 ceramic radome is calculated. Si 3 N 4 ceramics with graded porous structure are then prepared according to the design. The prepared sample exhibits a good graded porous structure with the porosity range from ∼ 2% to 63 %. The tested power transmission efficiency at 1-18 GHz for the obtained sample matches well with the calculation results, indicating that the graded porous structure is feasible for the broadband radome application.

“…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. For particular geometries, analytic methods are also possible [14].…”

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.
