Dual-Band Uniaxial Dielectric Anisotropy Sensor Using Coupled-Line Resonators
IEEE Access, 2023 In this paper, a new dual-band sensor to measure uniaxial anisotropy at two frequency bands is proposed. This sensor is composed of two dual-mode resonators separated by a T-shaped structure implemented in microstrip technology.

Response of IAR frequency scale to solar and geomagnetic activity in solar cycle 24
AIMS Geosciences, 2020 The ionospheric Alfvén resonator (IAR) is an integral element of the entire ionosphere-magnetosphere system. It plays an essential role in energy exchange and interaction between the magnetosphere and ionosphere.

Resonances of rectangular resonators [PDF]
The Journal of the Acoustical Society of America, 1981 We have used variational methods based on the work of Holland and Eernisse to predict the resonant frequencies of rectangular resonators for use in acoustic transducer arrays. We have predicted both the open and short circuited resonances and have compared the theoretical results obtained with a large number of experiments carried out on such ...

Nuclear Physics A, 2010 In this talk I show recent results on how many excited baryon resonances appear as systems of one meson and one baryon, or two mesons and one baryon, with the mesons being either pseudoscalar or vectors. Connection with experiment is made including a discussion on old predictions and recent results for the photoproduction of the $ (1405)$ resonance ...

Monolithic ultra-high-Q lithium niobate microring resonator [PDF]
, 2017 We demonstrate an ultralow loss monolithic integrated lithium niobate photonic platform consisting of dry-etched subwavelength waveguides with extracted propagation losses as low as 2.7 dB/m and microring resonators with quality factors up to 107.

Quantum squeezing of motion in a mechanical resonator [PDF]
Science, 2015 Manipulation of a quantum squeeze The uncertainty principle of quantum mechanics dictates that even when a system is cooled to its ground state, there are still fluctuations. This zero-point motion is unavoidable but can be manipulated.
