Résumé

In this paper an innovative manufacturing technology is presented that combines electroforming and CFRP application and thus could be an enabling technology to achieve tuningless lightweight RF passive hardware with complex geometries. In order to demonstrate the performances achievable with this manufacturing process, a highly sensitive 0.14% fractional bandwidth dual mode filter centered at 19.8GHz was fabricated and tested. The flange interface of the filter was an integral part of the hardware and the total weight four times lighter than an equivalent part made from INVAR.

Géométrie complexe

In mathematics, complex geometry is the study of geometric structures and constructions arising out of, or described by, the complex numbers. In particular, complex geometry is concerned with the study of spaces such as complex manifolds and complex algebraic varieties, functions of several complex variables, and holomorphic constructions such as holomorphic vector bundles and coherent sheaves. Application of transcendental methods to algebraic geometry falls in this category, together with more geometric aspects of complex analysis.

Complex analytic variety

In mathematics, and in particular differential geometry and complex geometry, a complex analytic variety or complex analytic space is a generalization of a complex manifold which allows the presence of singularities. Complex analytic varieties are locally ringed spaces which are locally isomorphic to local model spaces, where a local model space is an open subset of the vanishing locus of a finite set of holomorphic functions. Denote the constant sheaf on a topological space with value by .

Variété complexe

Les variétés complexes ou plus généralement les sont les objets d'étude de la géométrie analytique complexe. Une variété complexe de dimension n est un espace topologique obtenu par recollement d'ouverts de Cn selon des biholomorphismes, c'est-à-dire des bijections holomorphes. Plus précisément, une variété complexe de dimension n est un espace topologique dénombrable à l'infini (c'est-à-dire localement compact et σ-compact) possédant un atlas de cartes sur Cn, tel que les applications de changement de cartes soient des biholomorphismes.
