Reflection and Refraction Phenomenon of Waves At The Interface of Two Non-Local Couple Stress Micropolar Thermoelastic Solid Half-Spaces

We have discussed reflection and refraction phenomenon of wave propagation from a plane interface dividing the non-local couple stress micropolar thermoelastic medium into two half-spaces. we have examined the problem by making incidence of two sets of coupled longitudinal waves and two sets of coupled transverse waves. Here, we observed that there exist five waves, viz., two sets of coupled longitudinal waves, two sets of coupled transverse waves and a longitudinal microrotational wave in non-local couple stress thermoelastic micropolar solid. One of them is propagating independently while others are set of coupled waves. We have also observed that these waves are propagating with different speeds. By making incidence of different waves; the reflection and refraction coefficients of numerous waves against the angle of incidence and angular frequency has been evaluated and portrayed graphically.
