MIM is involved in research projects requiring expertise in the physics of electromagnetic wave-matter interactions. Researchers use microwave modelling and characterization tools to address complex problems in the following areas, ranging from the characterization of matter or structured materials to the study of new materials.

Presentation of the waves research activities of the ZeroPower Axis

Energy harvesters are realized thanks to a dual band rectenna (0.9 GHz, 2.45 GHz) able to power a 5μW digital clock.  The system is developed on a conformable substrate (Kapton) allowing a better adaptation on the environment and an improvement in terms of portability, weight, and manufacturing cost. As a continuation the team is now focusing on developing metamaterials based antenna for WBAN applications and hybrid energy harvester coupling RF and piezoelectric

The studies concern the conception of photonic crystals (microwaves domain) and electromagnetic behavior of metamaterials

Research focuses on the design of specific equipments for the monitoring of the environment (vegetation, soil, water) using in situ, continuous and non-intrusive electromagnetic measurements. As examples, the data collected makes it possible to improve knowledge of global warming (study of permafrost) or to study the effects of water stress on vegetation. This research also makes it possible to improve the permittivity estimation models of natural environments, essential for the data treatment of space remote sensing missions (SMOS, BIOMASS).

The MIM team has recognized expertise in microwave measurement tools associated with physical propagation or electromagnetic characterization models. Dielectric spectrometry allows to deduce from permittivity other physical quantities such as humidity, salinity or the density of a medium for the nondestructive testing. The team has several measurement and analysis benches over a wide spectral range, from DC to 110 GHz, to characterize a wide range of materials (homogeneous, heterogeneous media, conductive polymers, ceramics, carbon nanotubes, hydraulic concrete, natural media).

Numerous research results are stored in a database call CASEMAT (CAractérisation et Simulation Electromagnétique de MATériaux) accessible at http://casemat.ims-bordeaux.fr/ .

Results of measurements and simulation/modelling of wave/material and wave/structure interactions are stored  (70,000 data). This tool is useful to share our results with other researchers in the framework of collaborations. Free but limited access is allowed on a guest account (login: invite, pwd: invite).

Presentation of the ZeroPower research activities


Our research works especially involve the study of waves propagation, including emission / reception, and dynamical interaction mechanisms with solid, liquid or gaseous media. The realization of ultra-sensitive and reliable microsensors together with processing electronics is an overarching goal, towards embedded and communicating systems adapted to a digital environment. All projects are carried out in close collaboration within a multidisciplinary team (electronics, microtechnology, chemistry, biology, etc.) gathering local/national/international academic and/or industrial partners.
