Bessel beams: diffraction in a new light

for propagation in the z direction, the intensity, I, obeys: Iðx;yz 0Þ¼ Þð3Þ This means that there is no change in the cross-section as the beam propagates and thus the beam can be considered diffraction free, or propagation invariant. One way of thinking about the Bessel beam is to consider a set of plane waves propagating on a cone.

Ultrasound - University of Washington

Propagation of ultrasound waves in tissue •Ultrasound imaging systems commonly operate at 3.5 MHz, which corresponds to a wavelength of 0.44 mm when c = 1540 m/s. Refraction •When a wave passes from one medium to another the frequency is constant, and since c changes then so must the wavelength!= c f since λ2 < λ1 we have c2 <c1
