Over the past few years, the development of new generations of satellite systems, such as nano/micro/cube satellites, has fueled a considerable search for miniaturized microwave/mm-wave systems. Microwave filters are the main building blocks of passive devices, which typically rely on microstrip, dielectric, coaxial, and waveguide technologies. Waveguide filters are an ideal solution for space applications due to their low energy loss and high-power handling capabilities, with no frequency limitation. However, their main drawback is their large volume and high weight, as traditional designs directly scale with the operating wavelength.
Our MinWave project aims at developping a novel technique for manipulating waves over subwavelength volumes, and provide a new generation of compact waveguide devices for terrestrial and space applications. We leverage locally resonant metamaterials to manipulate microwaves and millimeter waves in ultra-small volumes. Our technique allows an innovative design framework to produce a wide range of components with various features in a small footprint, roughly one order of magnitude smaller than the devices currently available on the market, with no loss of performance or compatibility.
