Experimental realization of an open cavity
The design and experimental demonstration of an open cavity in the microwave region is presented. The resonance condition is achieved through the cancellation of lightpaths in positive and negative refractive index materials. The positive index material is a structured aluminium surface supporting a spoof surface plasmon mode, and the negative index material is a photonic crystal made of alumin...
متن کاملExperimental study of free convective heat transfer in a direction-sensitive open cavity
The aim of the present study was to propose a panel being sensitive to the direction of heat transfer. For this purpose, a vertical rectangular cavity with prescribed dimensions was prepared and filled with water as the working fluid. A vertical mid-plane solid partition was installed within the cavity. Two relatively wide openings were created at the top and bottom of the partition and they we...
متن کاملPoincaré Section Analysis of an Experimental Frequency Intermittency in an Open Cavity Flow
Open flows over a cavity present, even at medium Reynolds number, sustained oscillations resulting from a complex feedback process [1]. Previous works have reveals a mode-switching phenomenon which remains to characterize from a dynamical point of view. In the configuration here investigated, the intermittency between the two dominant modes is characterized using a symbolic dynamics based appro...
متن کاملExperimental Realization of an NMR Quantum Switch
In this paper, we report an experimental realization of quantum switch using nuclear spins and magnetic resonant pulses. The nuclear spins of H and C in carbon13 labelled chloroform are used to carry the information, then nuclear magnetic resonance pulses are applied to perform either bypass or cross function to achieve the switching. Compared with a traditional space or time domain switch, thi...
متن کاملAn Experimental Investigation of Cavity Flow
Understanding and controlling the flowfield in and around a cavity has challenged researchers for a number of years. The presence of a cavity on a body has been observed to significantly increase the mean drag, cause flow-induced vibrations and give rise to strong acoustic production. Of particular interest here are the flow structure and dynamics associated with open shallow rectangular caviti...
