Abstract (Swedish)
The effect of curvature on the performance of electromagnetic functional structures, such as electromagnetic absorbers and frequency selective surfaces, is investigated in this work. The monostatic radar cross section of a doubly curved, rotationally symmetric scatterer, with and without a coating electromagnetic absorber, is calculated. An analytical expression for calculating the far-field from the electric and magnetic fields of a single azimuthal mode excitation in circular polarization has been derived, in order to achieve fast and efficient full wave simulations. It is concluded that the effect of curvature is more severe for absorbers based on resistive sheets that for absorbers based on bulk loss.
