Abstract :
The paper presents efficient full wave analysis of electrically large multilayered radomes, which are based on advanced MoM techniques: 1) higher order basis functions, 2) "smart reduction" of expansion orders, 3) excitation of structure by field generators, 4) equidistant positioning of dielectric surfaces based on equal meshing of all layers, 5) direct solution of matrix equation based on LU decomposition, 6) out-of-core matrix solver, and 7) CPU and GPU parallelization. Results for A-sandwich radome of 8 λ in diameter, which are obtained in 7 minutes at PC, are shown for different beam steering angles. Two different A-sandwich radomes with 16 λ in diameter are shown in order to illustrate influence of the middle layer thickness on the radiation pattern. Finally, the radiation pattern of the array with a radome which diameter is equal to 60 λ is shown.
