Complex WGM frequencies of gyroelectric cylindrical resonators

IET Microwaves, Antennas & Propagation, 2021
Asymptotic closed‐form expressions for calculating complex transverse electric (TE)/transverse magnetic (TM) whispering gallery mode (WGM) frequencies in homogeneous gyroelectric circular cylindrical resonators of infinite length are derived. In addition,

Wave separation in the trumpet under playing conditions and comparison with time domain finite difference simulation [PDF]

, 2013
Wave separation within a trumpet is presented using three high pressure microphones to measure pressure waves within the curved, constant cross-section tuning slide of the instrument while the instrument was being played by a virtuoso trumpet player.

Cylindrical Resonator Sectorally Filled With DNG Metamaterial and Excited by a Line Source [PDF]

, 2012
A circular cylindrical resonator with metallic walls is analyzed in the phasor domain. The resonator contains a wedge of double-negative (DNG) metamaterial that is anti-isorefractive to the double-positive (DPS) material filling the remaining volume of ...

EXACT OBSERVABILITY OF A 1D WAVE ON A NON-CYLINDRICAL DOMAIN [PDF]

, 2019
We discuss admissibility and exact observability estimates of boundary observation and interior point observation of a one-dimensional wave equation on a time dependent domain for sufficiently regular boundary functions.

3D THz-TDS SAR Imaging by an Inverse Synthetic Cylindrical Aperture

IEEE Access, 2023
Terahertz time-domain spectroscopy (THz-TDS) is a promising tool for high-resolution 3D imaging of objects due to the high center frequency and bandwidth compared to microwave systems.

Logarithmic wave equations in non-cylindrical domains

, 2021
This paper is devoted to studying a type of logarithmic wave equation in non-cylindrical domains. Firstly, by the penalty method, we prove the existence of weak solutions to such kind of equations. Secondly, different from the dissipative wave equation, the energy defined in this problem is not always positive.
