Webb22 aug. 2024 · This factor leads to a much slower cycling speed of smooth muscle. However, ... The slow waves are, therefore, able to allow the smooth muscle to remain tonic without having to maintain continuous action potential firings. Research has shown that smooth muscle can contract without any action potential.
Webb5 juli 2024 · We report the results of the design, simulation, fabrication, and cold-test measurements of millimeter-band 2D planar microstrip slow-wave structures (SWSs) on dielectric substrates. Such... Slowing factor: the ratio of the wave wavelength of a "native" transmission line to the wavelength in a slow-wave structure. The higher the slow-wave factor, the more the transmission line's wavelength is reduced compared to its "normal" wavelength in the chosen dielectric medium. Visa mer This class of circuits are related to "artificial" transmission lines (an artificial transmission line uses lumped inductors and capacitors that obey the telegraphers equations). Note that there are many physical … Visa mer In the case of transmission lines, the onset of a stop band for electromagnetic waves in a periodic structure corresponds to Bragg reflection in crystals. In 1915, William Henry Bragg … Visa mer This type of slow-wave structure is less well known. Silicon is usually a very poor insulator.
