Angular spectrum method

This is code computes the time domain response of a transmitter-layered media-receiver setup. Ofte then layer medium is a plate with a surrounding medium, often some kind of fluid or gas.

Implemented features

• Pulse-echo setup
• Throughtransmission
• (Misalignment) angle between transmitter and the layered media
• Displaced receiver from the acoustical axis
