This paper contains an overview of the homogenization of anisotropic materials at fixed frequency using the concept of two-scaled convergence. The homogenized electric and magnetic parameters, the relative permittivity and the relative permeability, respectively, are found by suitable averages of the solution of a local problem in the unit cell. A comparison between the exact homogenization method
This research is triggered by the emerging ‘power by the hour’® paradigm, in which aero engines are effectively leased to airlines, with the manufacturing company remaining responsible for their maintenance and repair throughout their service life. By incorporating knowledge about the performance of existing products into the design phase of new products, it is hoped to tackle some of the in-servi
In order to reduce the monostatic signature of the junction between a radome and the metallic structure to which it is attached, a tapered resistive sheet can be used. In this paper, we describe an easy method to realize this tapering using geometric variations on a subwavelength scale, with a significant reduction of the number of processing steps as a result.
