In a travelling wave tube, the wire helix is supported at a few points in each turn by a surrounding tube of, e.g. square or triangular cross-section, whereby the effect of irregularities in the supporting dielectric tube are minimized, and space is provided for the extra thickness at ...
3. Determining the Shape of the Wave Front: - As the light waves propagate from the line source, they form wave fronts that are perpendicular to the direction of wave propagation. 4. Identifying the Type of Wave Front: - For a line source, the wave fronts will take the shape of ...

Shaking a towel up and down would create what type of wave in the towel? a) transverse b) longitudinal c) surface What type of waves is possible in the case of solids? What are the uses of each electromagnet wave? What is the wave-particle duality? What is a Wave-Particle Duality? W...
Love wave; temperature characteristics Abstract As a piezoelectric substrate for surface acoustic wave devices, the LST cut quartz has good temperature characteristics and low propagation loss. However, as the thickness of the metal electrodes on the substrate surface is increased, propagation loss also...
Generalized Love-type wave propagation in a nonlinear, heterogeneous, isotropic, low-velocity intermediate layer of uniform thickness lying between two nonlinear, homogeneous, elastic, different half-spaces is examined. The heterogeneity of the layer is considered to result from the exponential change of...
of ideal “frozen wave”-type beams inside the stratified structure is also proposed. Examples of field reconstructions are provided for two- andN-layer media which show that the proposed method is capable to recreate surface intensity patterns, in the millimeter domain, with good fidelity and ...
This study illustrates the useof CPCs as a waveguide layer to modulate the propagation of Love-typewaves and explores their application prospects for swelling monitoring. 展开 关键词: swelling layered structure conductive polymer composites surface acoustic wave device Love-type wave ...

Traveling wave propagation is generated on the TFMG pipe in finite element method (FEM) simulations and also observed in the measurement. Bi-directional motion of the slider was observed around 600 kHz, and the maximum velocity was about 40 mm/s at 25 V. 展开 ...
