Metamaterials are artificially engineered devices that go beyond the properties of
conventional materials in nature. Metamaterials allow for the creation of negative refractive …

This article presents a metal-only reflectarray that enables the control of incident orthogonal
polarizations in a large bandwidth. The proposed reflectarray is based on a unit cell whose …

This chapter intends to show the strong potential brought by metal 3D-printing to the field of
waveguide components and antennas. General co-design guidelines are firstly provided …

This work presents the complete design process of a 3-D fully metallic reflectarray. The
structure is composed of two unit cells with resonators in the z-direction that are phase …

This work employs a new approach to analyze coupled-resonator circuits to design and
manufacture a fully metallic dual-polarization frequency-selective surface (FSS). The …

polarizations in a large bandwidth. The proposed reflectarray is based on a unit cell whose …

This thesis is carried out in partnership with the European Space Agency (ESA) and the
company SWISSto12, as part of an ESA OSIP activity. The work concerns the development …

This work presents the complete design process of a 3D fully-metallic reflectarray. The
structure is composed of two unit cells with resonators in z direction that are phase-shifted …
