A Highly Compact ZOR based on CRLH TL [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2017
Design and development of a highly compact zeroth order resonator (ZOR) based on composite right/left handed transmission line (CRLH TL) is reported in this paper. The ZOR is based on single unit-cell CRLH TL.

On the treatment of connecting conditions and the choice of admissible functions in energy method to investigate band gap characteristics of periodic beams

open access: yesMechanical Engineering Journal
Periodic structures are known to have specific frequency ranges called band gaps, where the transmission of elastic waves is suppressed. Research on band gap formation in mechanical structures has recently gained considerable attention, and there is a ...

Phononic Crystal Made of Silicon Ridges on a Membrane for Liquid Sensing

open access: yesSensors, 2023
We propose the design of a phononic crystal to sense the acoustic properties of a liquid that is constituted by an array of silicon ridges on a membrane. In contrast to other concepts, the ridges are immersed in the liquid. The introduction of a suitable

Common shape of the dispersion curve.

open access: yes, 2017
In the stationary state spatial structures (right pane) have a period which in many cases can be approximately predicted from the dispersion curve (left pane). Self-exited and damping spatial waves are shown with red and dashed lines, respectively.

Sabot Front Borerider Stiffness vs. Dispersion: Finding the Knee in the Curve [PDF]

open access: yes, 2001
In the design of armor piercing, fin-stabilized, discarding sabot projectiles, the radial stiffness of the sabot front borerider has a significant impact on the projectile's dispersion and is, therefore, an important design consideration.

Modelling Of Phased Array Technique To Propagation Specific Mode Of Ultrasonic Waves In Single And Multi-Layer Plates [PDF]

open access: yesمجله مدل سازی در مهندسی, 2015
In this paper, the propagation of ultrasonic guided wave in the isotropic single-layer and multi-layer plate with the assumption that layers are fully connected to each other and top and bottom surfaces of plate are free stress, are investigated and the ...

Automatic Extraction of Surface Wave Dispersion Curves Using Unsupervised Learning and High‐Resolution Tau‐p Transform

open access: yesEarth and Space Science, 2023
Dispersion curves for surface wave recordings are required input for many surface wave inversion methods to image subsurface shear wave velocity distribution, while the conventional extraction of dispersion curves requires significant amount of human ...

Determination of the dispersion curve of the refractive index by the Stockwell transform

open access: yes, 2009
The determination of dispersion curves by the Stockwell transform (ST) is proposed. The required numerical data for dispersion curves are produced from the transmittance signal by the ST. The obtained data are then used to estimate the unknown dispersion
