Research on Attenuator Type OWC Wave Power Absorber (2nd Report)

Analytical Investigation of the Effects of a Standing Ocean Wave in a Wave-Power Device OWC

In this work we study analytically and numerically the performance of the mean heave motion of an OWC coupled with the governing equation of the spreading ocean waves due to the wide variation in an open parabolic channel with constant depth. This paper considers that the ocean wave propagation is under the assumption of a shallow flow condition. In order to verify the effect of the waves in th...

Final Report Project Name: Research on Novel High-power Microwave/millimeter Wave Sources and Report Documentation Page Research on Novel High-power Microwave/millimeter Wave Sources and Applications

Performance characteristics of a fundamental cyclotron harmonic, distributed-loss, TE01-mode gyrotron traveling-wave amplifier are studied theoretically. Absolute instabilities on both lower and higher order modes at the fundamental and second cyclotron harmonic frequencies present a severe limitation to the stable operating current and hence the device capability. General methods for stabilizi...

Investigation of the effect of geometry float body on the power of wave energy absorber converter using mooring catenary

This paper presents the effect of hydrodynamic parameters of the two-body converters of a point wave absorber on the amount of power output. This converter includes two submerged and floating bodies which are connected to the spring-damper system. The whole of the converter is connected to the sea bed by mooring catenary. The relative displacement of the floating body and the submerged body is ...

Optically Tunable Millimeter-wave Attenuator Based on Layered Structures

A new type of optically controllable, millimeter-wa e ( ) ( ) ( ) MMW attenuator based on high-resisti ity high-R silicon Si wafers and a layered structure is de eloped. A high-R float-zone Si wafer is a lossless dielectric material at microwa e frequency without optical excitation. When an Si wafer is optically excited, free carriers are generated, and the Si wafer becomes a lossy dielectric. ...
