Pn 2.3.3 Standing Waves or Resonances When a free progressive wave encounters a sharp change in impedance such as at an air-hardwall boundary, and if the angle of incidence is normal, then the reflected wave travels back along the original path of propagation with a 360 ° change in phase.

Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

For example, all previous theoretical predictions and experimental observations have been questioned by Valanju et,wherein the authors claim that the presence of dispersion prevents power transmitted at RHM-LHM interface from refracting at a negative angle, which means the refraction of group velocity n_g carrying the physics information isall along positive refraction, but "negative refractive material " means only the refraction of phase velocity np is negative.

涉及最多的是负折射现象在物理上的因果率，例如Valanju等人通过一些理论计算认为所谓的"负折射率材料"只是相速的折射率n_p可以是负的，而携带物理信号的群速度的折射率n_g永远是正的，由此引发了许多争议。
