Recent advances in cavity-based scramjet engine- a brief review

International Journal of Hydrogen Energy, 2019
At present, the critical issue related to design of scramjet engine is to achieve efficient mixing between the air and fuel. Among the several fuel injection strategies, cavity flame holder is identified as a well-organized method for supporting the ...

Dual-Band Microwave Sensor Based on Planar Rectangular Cavity Loaded With Pairs of Improved Resonator for Differential Sensing Applications

IEEE Transactions on Instrumentation and Measurement, 2021
A dual-band sensor based on a planar rectangular cavity loaded with pairs of improved planar resonator is used to measure the permittivity difference of liquids with a small volume ( $2.5~\mu \text{l}$ ).

Cavity-mediated thermal control of metal-to-insulator transition in 1T-TaS_2

Nature, 2022
Cavity-mediated thermal control of metal-to-insulator transition is achieved by embedding the charge density wave material 1T-TaS_2 into cryogenic tunable terahertz cavities.

Cavity-enhanced spectroscopy in fiber cavities

Optics Letters, 2004
We discuss the relative merits of passive and active fiber cavities for ring-down. Ring-down times of approximately 2 micros were recently demonstrated in passive cavities, but operation is restricted to weak evanescent wave interaction. We report on active cavities with amplifiers used for loss compensation, permitting the use of open-path micro-optic

Perigraft cavity

Cardiovascular and Interventional Radiology, 1981
A case is reported of an unusual sinographic appearance and negative microbial cultures, indicating a long-term failure of incorporation of a vascular graft by surrounding connective tissue. Possible pathogenic mechanisms include ruptured lymphatic channels or a low-grade immunologic rejection process.
