  Geneva Area, Switzerland The detection or exclusion of Weakly Interacting Sub-eV Particles (WISPs), like hidden-photons or axions, is one of the fundamental questions of modern physics. In the framework of this PhD, a table-top experiment has been designed, constructed and operated to probe WISPs with microwaves techniques.

In the framework of this PhD, a table-top experiment has been designed, constructed and operated to probe WISPs with microwaves techniques. If WISPs exist, theory predicts a weak coupling between two microwave cavity resonators, which is not of electromagnetic origin. Driving one cavity with a powerful microwave signal and listening on the other one with a sensitive microwave receiver, we try to observe this coupling. Mitigating electromagnetic interference is critical. Key points: * Construction of a phase locked hetrodyne receiving chain, able to detect a narrow-band microwave signal down to -210 dBm (10^-24 W or 0.5 photons/s) at room temperature. This is made possible by narrow-band filtering with resolution bandwidths in the micro-Hz range * High end electromagnetic shielding for the detection part of the experiment. An overall 300 dB of signal attenuation has been achieved within a distance of 15 cm for 3 GHz signals. This was done using several custom made shielding boxes stacked into each other. All signals are transmitted over optical fibres.
