Cancer Drug resistance is a medical concern that requires extensive research and a thorough understanding in order to overcome. Remarkable achievements related to this field have been accomplished and further work is needed in order to optimize the cure for cancer and serve as the basis for precise medicine with few or no side effects.

Reflection and transmission of plane elastic waves in porous piezo-thermoelastic laminated plate immersed in a fluid has been studied. A theoretical model is derived which is based on transfer matrix method. The layered structure is considered to be consisting of ‘n’ number of layers of porous piezo-thermoelastic materials immersed in a fluid. All the layers are considered to be 2 mm PPTE materials. The formal solution for the mechanical displacements, electric potential, mechanical stresses, electric displacements, temperature changes and temperature gradient are derived. The transfer matrix technique is used to study the layered materials. The closed form expressions of the elements of transfer matrix are derived. The analytical expressions for the reflection coefficient and transmission coefficient are derived. The effects of frequency, angle of incidence, number of layers, layer’s thickness and porosity on the reflection coefficient and transmission coefficient, reflection loss and transmission loss are investigated numerically for different configurations. Particular cases of the present study have also been obtained for the verification of the results.
