چکیده

Parametric transducers, such as superconducting rf cavities, can boost the bandwidth and sensitivity of the next generation resonant antennas, thanks to a readily available technology. We have developed a fully coupled dynamic model of the system ”antenna– transducer” and worked out some estimates of signal–to–noise ratio and the stability conditions in various experimental configurations. We also show the design and the prototype of a rf cavity which, together with a suitable read–out electronic, will be used as a test bench for the parametric transducer.

, e . g . , superconducting transducers between electromagnetic and gravitational radiation ?

One of the conceptual tensions between quantum mechanics (QM) and general relativity (GR) arises from the clash between the spatial nonseparability of entangled states in QM, and the complete spatial separability of all physical systems in GR, i.e., between nonlocality implied by the superposition principle, and locality implied by the equivalence principle. Experimental consequences of this co...

Superconductors as transducers and antennas for gravitational and electromagnetic radiation

Type II superconductors will be considered as macroscopic quantum gravitational antennas, which can simultaneously also be used as efficient transducers for converting electromagnetic radiation into gravitational radiation, and vice versa. A Meissner-like effect, in which the LenseThirring field associated with a gravity wave is expelled from the interior of the superconductor, is predicted. An...

Design and Development of High Gain, Low Profile and Circularly Polarized Cavity-backed Slot Antennas Using High-order Modes of Square Shaped Substrtae Integrated Waveguide Resonator

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
