Focussing and defocussing of ballistic phonons in diamond and $ Nb_{3} $Sn
Abstract The ballistic propagation of phonons in diamond and $ Nb_{3} $Sn at 40 and at 4.2 K is examined. The nature of variation of the phonon magnification factor has been analysed both in the wave vector as well as group velocity spaces. Using the Polar Schmidt-net with Pole at (π/2,π/2), the map...

Focussing and defocussing of ballistic phonons in diamond and $ Nb_{3} $Sn |
| abstract |
Abstract The ballistic propagation of phonons in diamond and $ Nb_{3} $Sn at 40 and at 4.2 K is examined. The nature of variation of the phonon magnification factor has been analysed both in the wave vector as well as group velocity spaces. Using the Polar Schmidt-net with Pole at (π/2,π/2), the mappings of phonon focussing and defocussing are made. It is shown that the mapping for theFTA mode for $ Nb_{3} $Sn exhibits islands acting as impenetrable barriers for phonon propagation. © the Indian Academy of Sciences 1985 |

Abstract The ballistic propagation of phonons in diamond and $ Nb_{3} $Sn at 40 and at 4.2 K is examined. The nature of variation of the phonon magnification factor has been analysed both in the wave vector as well as group velocity spaces. Using the Polar Schmidt-net with Pole at (π/2,π/2), the mappings of phonon focussing and defocussing are made. It is shown that the mapping for theFTA mode for $ Nb_{3} $Sn exhibits islands acting as impenetrable barriers for phonon propagation. © the Indian Academy of Sciences 1985 |
