Definitions

  • the invention is related to Classics wave theory for calculation the reflectivity of the interface of resonance wave when wave through the interface or the interface of the transition zone.
  • the methods of this invention will be widely used that wave spread through the interface in various fields such as light, electromagnetic waves, sound wave, water wave and so on for resonance wave that have both refractive wave energy and reflective wave energy.
  • This theory solving the problem method is first to find out the interface area of resonance wave as inner the boundary; second to calculate the ratio of both transmission (refraction) and reflection wave energy, and to calculate the angle of separately wave travel direction; and then third as the inner boundary refractive wave as new incident wave go to refractive area, and reflective wave as new incident wave go to the area of incident wave with initial value to calculate.
  • the formulas are derived by ratio of both incident normal component and refractive wavelength for the resonance reflectivity.
  • reflection wave energy is begin to emerge when the normal component of incident wavelength through the interface is compressed to the resonance wavelength near three quarters of wavelength of the refraction wave. Following Angle of incidence wave change and the ratio of the wavelength gradually being compressed, it is increase gradually for reflection wave energy.
  • the reflection wave energy is half value of incident wave energy when the ratio of the normal component of incident wavelength being compressed to a half wavelength of the refraction wave.
  • the incident wave energy could all be reflected when the normal component of incident wavelength is compressed to a quarter wavelength of the refraction wave.
  • the angle of incident wave is less than or equal to the angle of resonant reflection critical means ⁇ 0 ⁇ R , or the coefficient of compressibility is m ⁇ m R ,
  • the transition zone biggest role is set Mutation interface up soft and smooth, it is slow for wave travelling that the interface of mutation could block and produce to reflected wave energy, and even can eliminate the reflected wave energy, the incident wave go into pure transmission or refraction wave.
  • a steep cliff On the other side is a gentle slope, It is easily for the people that go to the top of the mountain by other side of a gentle slope, and it is difficulty to climb the steep cliff.
  • the first step to calculate the interface reflectivity and transmission rate as shown in Fig 8. And then we may calculate the transmission rate of the refraction wave energy after the first step. Among various order no reflection wave energy, only the last order have the reflection wave energy.
