Lattice Dynamics Kit

Lattice dynamics is an essential component of any postgraduate course in Physics, Engineering Physics, Electronic Engineering and Material Science. In particular it is essential fro understanding the interaction of electromagnetic waves and crystalline solids.

The following experiments may be performed with the help of this kit:

- Study of the Dispersion relation for the “Mono-atomic Lattice” and Comparison with theory.
- Determination of the Cut-off frequency of the Mono-atomic Lattice.
- Study of the Dispersion relation for the Di-atomic Lattice, Acoustical mode and Energy gap. Comparison with theory.

Setup consists of :

• Audio oscillator with amplitude control and facility to vary the frequency from 0.9 KHz to 90 KHz ,
• Transmission line, which simulates one-dimensional mono-atomic and di-atomic lattices,
• Output stage to match the impedance of simulated lattice.
