11. The voltage reflection coefficient and current reflection coefficient on the same side have opposite signs. 12. The reflection coefficient determines the ratio of the reflected wave amplitude to the incident wave amplitude. 13. Therefore, the complex valued reflection coefficient \ Gamma varies as well, but only in phase. 14. However, to completely characterise the reflection coefficient , the phase of ? must also be found. 15. This is effectively a mirror with a reflection coefficient greater than 100 %, producing an amplified reflection. 16. APC-7 connectors are advantageous because they have a low-reflection coefficient , make repeatable genderless. 17. The reflection coefficient can be as low as 0.105 but is usually near 0.5. 18. And this tells you very little about the reflection coefficient at the precise wavelengths that your laser emits. 19. This is correct for reflection coefficients with a magnitude no greater than unity, which is usually the case. 20. After the seismic wavelet is estimated, it is used to estimate seismic reflection coefficients in the seismic inversion.
