Fast Multilayer Radome Computation with Gaussian Beams
We propose a technique to compute the effect of a dielectric multilayer radome. This technique uses a gaussian beam expansion associated with an evaluation of the physical optics spectral integrals using the asymptotic steepest descent path method. Then, we compare an iterative and a global process to take into account the multiple reflections inside the radome. Finally, a numeric validation is...
متن کاملEM Performance Improvement of a Large A-type Sandwich Radome
Large sandwich radomes are widely used for radar antennas because of the desired some characteristics. They are constructed by connecting small panels for the restrictions on manufacture. These connection parts yield undesired scattered waves and generate higher sidelobes. We present a novel method to overcome this problem by optimizing the radome geometric design. The scattering characteristic...
متن کاملSeveral Related Models for Multilayer Sandwich Plates
Mathematical models for multilayer sandwich plates consisting of alternating stiff and compliant layers are derived. Two main types of models are described. First an initial model (analogous to the three-layer Rao-Nakra model) is derived under Kirchhoff plate assumptions for the stiff layers and Mindlin shear-deformable displacement assumptions for the compliant layers. The second type of model...
متن کاملFlat Parametric Counter Automata
In this paper we study the reachability problem for parametric flat counter automata, in relation with the satisfiability problem of three fragments of integer arithmetic. The equivalence between non-parametric flat counter automata and Presburger arithmetic has been established previously by Comon and Jurski [5]. We simplify their proof by introducing finite state automata defined over alphabe...
متن کاملBroadbanding of A-sandwich Radome Using Jerusalem Cross Frequency Selective Surface
Enhancement of electromagnetic performance of A-sandwich radome using aperture-type Jerusalem cross frequency selective surface (FSS) is presented. The Jerusalem cross FSS array is embedded in the mid-plane of the core of Asandwich radome to enhance the EM performance parameters over the entire Xband. For modeling the Jerusalem cross FSS embedded radome panel and evaluation of its EM performanc...
