“…It is clear that, the result of L = 8 has obvious differences with the direct integration result, however, the results of L = 10 and 12 agree very well with it. As discussed in (12), when L = 8, the Figure 7. Calculated H plane radiation patterns using AI-SI with fast multipole acceleration compares with the result in [7] calculated by direct integration.…”

“…In FMM, the triangles on the aperture and radome are divided into groups with the maximal diameter d max = 1.25λ. In order to obtain enough accuracy, the parameters in (12) are chosen as γ = 1 and L = 10, thus the relative error of FMM result can be less than 0.1. The Gauss-Legendre integration number is K = 2L 2 = 200.…”

“…R ⊥ , R // , T ⊥ , T // are the reflection and transmission coefficients for the perpendicular and parallel polarization components [7,20]. The reflected fields on the inner surface may bounce in the radome and they have important effects on the flash lobe of the antenna-radome system [12][13][14]. In order to account the mutual interactions between different parts of the radome, the fields radiated from the reflected fields must be calculated.…”

“…Some portion of the first incident fields will transmit through the radome wall and the remaining will be reflected by the wall. The reflected fields have important effects on the flash lobe of the radiation pattern [12][13][14]. By integrating the reflected fields over the inner surface of the radome, the second incident fields on the inner surface of the radome can be obtained.…”

Abstract-Radome has strong effects on the radiation performances of the antenna in millimeter wave band. In this paper, the aperture integration-surface integration (AI-SI) method is adopted to analyze the electrically large antenna-radome system. The fast multipole method (FMM) is proposed to accelerate the aperture integration and inner surface integration in the AI-SI method. An electrically large antenna-radome system at W band is analyzed and measured. The radiation patterns of the system calculated using the AI-SI method with and without the fast multipole acceleration and the measured patterns are compared. The calculated patterns agree very well with each other, and both have the same agreement with the experimental results. However, the computational time of the proposed analysis with the fast multipole acceleration is reduced significantly.

Abstract-More accurate hybrid PO-MOM process combining physical optics (PO) with method of moment (MOM) is employed to analyze an electrically large antenna-radome structure. The mutual interactions among the antenna, the inner and outer surfaces of the radome are considered through a group of associated integral equations. In the analysis, the antenna surface and the sharp tip part on the radome surface are modeled accurately by using MOM while the rest smooth parts on the radome surfaces are approximated by using PO. Numerical results indicate that the hybrid process presented in this paper is much more accurate than the conventional PO-MOM ones.

Analysis of the elliptic-profile cylindrical reflector with a non-uniform resistivity using the complex source and dual-series approach: H-polarization case

An elliptic-profile reflector with varying resistivity is analyzed under the illumination by an H-polarized beam generated by a complex-source-point (CSP) feed. The emphasis is done on the focusing ability that is potentially important in the applications in the optical range related to the partially transparent mirrors. We formulate the corresponding electromagnetic boundary-value problem and derive a singular integral equation from the resistive-surface boundary conditions. This equation is treated with the aid of the regularization technique called Riemann Hilbert Problem approach, which inverts the stronger singular part analytically, and converted to an infinite-matrix equation of the Fredholm 2nd kind. The resulting numerical algorithm has guaranteed convergence. This type of solution provides more accurate and faster results compared to the known method of moments. In the computations, a CSP feed is placed into a more distant geometrical focus of the elliptic reflector, and the near-field values at the closer focus are plotted and discussed. Various far-field radiation patterns including those for the non-uniform resistive variation on the reflector are also presented. © 2013 Springer Science+Business Media New York
