Abstract
In-depth analysis of the propagation of an acoustic signal excited by a short radio pulse is performed. The signal is reflected from the simple lens of a scanning acoustic microscope, and its power is detected. An expression for V(z) curve (acoustic signature of a material) is derived. It takes into account excitation conditions (delay and recording times of a signal to be detected) and lens parameters.
