Adaptive-Passive Quarter-Wave Tube Resonator Silencer
An adaptive-passive quarter-wave tube resonator silencer was experimentally tested using recorded in-duct reciprocating engine exhaust noise. The exhaust noise was re-played through a loudspeaker attached to one end of a duct, and the adaptive passive system was able to track changes in engine speed and provide attenuation of the noise at the fundamental firing frequency of the engine and the t...
متن کاملNiobium Quarter-wave Resonator Development for the Rare Isotope Accelerator
There is a growing interest in the production of intense beams of exotic isotopes for research in nuclear physics and laboratory astrophysics [1]. The Rare Isotope Accelerator (RIA) is one such project being pursued by the nuclear physics community in the USA [2]. RIA calls for a superconducting cavity linac to accelerate the CW beam of heavy ions to ≥ 400 MeV per nucleon, with a beam power of ...
متن کاملDesign and Analysis of Ultra-wide Band Bandpass Filter Using Spiral Stub-Loaded Triple-Mode Resonator with a Notched Band
An ultra-wide band band-pass filter using novel spiral stub-loaded triple-mode resonator (SSLTMR) is presented. New spiral stub loaded resonator is analyzed with odd and even modes analysis for this class of BPF, achieving higher band wide and size reduction. In order to have a good response characterized, two (SSL-TMRs) and two quarter wavelength digital coupled lines are used. This new design...
متن کاملUltrathin Terahertz Quarter-wave plate based on Split Ring Resonator and Wire Grating hybrid Metasurface
Planar metasurface based quarter-wave plates offer various advantages over conventional waveplates in terms of compactness, flexibility and simple fabrication; however they offer very narrow bandwidth of operation. Here, we demonstrate a planar terahertz (THz) metasurface capable of linear to circular polarization conversion and vice versa in a wide frequency range. The proposed metasurface is ...
متن کاملQuarter-Wave-Shifted DFB Lasers
High-coupling (KL = 3.0) phase-shifted DFB lasers are studied using a transmission-line laser model (TLLM), which includes spatial hole burning (SHB), the material gain spectrum, refractive index dependence on carrier concentration, and random spontaneous emission. Good agreement for CW spectra is shown with other models and experimental results. Dynamic simulations of laser transients show SHB...
