In this paper we investigate dual synchronization and dual-cross synchronization between the transmitter and receiver, each one consisting of two master and slave systems. We demonstrate our approach using the example of synchronization of chaotic external cavity laser diodes. In the synchronization scheme under consideration the joint error signal, which is the difference between the sum of th...

Lasers with cavities consisting of retroreflecting elements can give the potential for large-dynamic-range alignment-free operation, which makes important applications in adaptive wireless laser power transfer/communication possible. In such an emerging approach based on resonant beam cavity, is delivered to photovoltaic cell charging application (or photodiode communication application) at rec...

We report on initial measurements of the low-temperature thermal properties of a device that is similar to the experimental apparatus used for absolute cryogenic radiometry (ACR) within the Low Background InfraRed (LBIR) facility at NIST. The device consists of a receiver cavity mechanically and thermally connected to a temperature-controlled stage through a thin-walled polyimide tube which ser...

This paper describes a dynamic model of a steam cavity receiver and presents results from simulations performed using this model in TRNSYS 16. The results are compared with experimental data to inform the calibration of specific model parameters. Using the experimental data obtained from the SG4 500 m2 dish at the ANU, it is possible to select a set of model parameters that produce good agreeme...

Time reversal acoustics (TRA) has gained widespread applications for communication and measurements. In general, a scattering medium in combination with multiple transducers is needed to achieve a sufficiently large acoustical aperture. In this paper, we report an implementation for a cost-effective and compact time reversal emitter-receiver driven by a single piezoelectric element. It is based...
