WebThe frequency dependence arises from the fact that, even though the fracture is assumed to be an interface of zero thickness, it still has at least two characteristic widths that provide the length scales necessary for scattering dependence on wavelength. WebApr 10, 2024 · Introduction Multiple rib fractures (≥ 3 displaced rib fractures and/or flail chest) are severe chest trauma with high morbidity and mortality. Rib fixation has become the first choice for multiple rib fracture treatment. However, the timing of surgical rib fixation is unclear.

Figure 10.1.1: A plane wave, Ex = E0exp(i[kz − ωt]) is incident from vacuum on a material characterized by a dielectric constant ϵ at the circular frequency ω. The wave falls upon the surface at normal incidence. The amplitude of the reflected wave is E R, and the amplitude of the transmitted wave is E T.
