Impedance Boundary Conditions on The Optimal Design of the H-Type Cylinder Resonator Using Transmission Matrix Method and Genetic Algorithm
Main Article Content
Abstract
Optimization of the H-type cylinder resonator design is very important in order to obtain maximum acoustic wave signal in photoacoustic. Geometrically, this resonator is in the form of three cylinders arranged axis-symmetric where the middle cylinder (resonator) is flanked by two other cylinders (buffer) giving sudden contraction and expansion. Impedance boundary conditions are used to analyze the waves propagating in this resonator. The method used in this optimization is the transmission matrix method (TMM) and genetic algorithm (GA), in which the transmission loss (TL) at a certain frequency and quality factor ( ) are treated as optimization objectives for the cell performance, whereas the resonator geometry dimensions are treated as optimization.

Journal author rights
In order for Romanian Journal of Acoustics and Vibration to publish and disseminate research articles, we need publishing rights. This is determined by a publishing agreement between the author and Romanian Journal of Acoustics and Vibration. This agreement deals with the transfer or license of the copyright to Romanian Journal of Acoustics and Vibration and authors retain significant rights to use and share their own published articles. Romanian Journal of Acoustics and Vibration supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in Romanian Journal of Acoustics and Vibration proprietary are defined below:
For subscription articles:
Authors transfer copyright to the publisher as part of a journal publishing agreement, but have the right to: Share their article for personal use (manuscript version); retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
For open access articles:
Authors sign an exclusive license agreement, where authors have copyright but license exclusive rights in their article to the publisher. In this case authors have the right to: share their article in the same ways permitted to third parties under the relevant user license; retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
Rights granted to Romanian Journal of Acoustics and Vibration
For both subscription and open access articles, published in proprietary titles, Romanian Journal of Acoustics and Vibration is granted the following rights:
- The exclusive right to publish and distribute an article, and to grant rights to others, including for commercial purposes;
- For open access articles, Romanian Journal of Acoustics and Vibration will apply the relevant third party user licence (Open access licencses) where Romanian Journal of Acoustics and Vibration publishes the article on its online platforms;
