| 1. | This can produce a negative index of refraction in the optical range.
|
| 2. | DNG can provide phase compensation due to their negative index of refraction.
|
| 3. | Suessite, as determined from the previous definition, only has one index of refraction.
|
| 4. | Optical fibers typically include a cladding material with a lower index of refraction.
|
| 5. | Additionally, one of the effects most studied is the negative index of refraction.
|
| 6. | It is optically isotropic with an index of refraction of n = 2.24.
|
| 7. | The ultrasound waves create changes in the air's index of refraction.
|
| 8. | This test achieved its goal because it successfully verified a negative index of refraction.
|
| 9. | Optical materials with varying index of refraction are called gradient-index ( GRIN ) materials.
|
| 10. | The radiance divided by the index of refraction squared is invariant in geometric optics.
