    This study presents an exact method to find spatial communication channels and their strengths between two volumes for scalar waves. The sum of squared strengths is shown to be a simple volume integral, with modes resembling a double phase-conjugate resonator.

    Area of Science:

    • Physics
    • Acoustics
    • Electromagnetics

    Background:

    • Understanding wave propagation between volumes is crucial in various scientific fields.
    • Characterizing spatial channels and connection strengths is essential for signal transmission and analysis.

    Purpose of the Study:

    • To develop an exact and complete method for identifying orthogonal spatial channels between two arbitrary volumes.
    • To determine the associated connection strengths for scalar wave propagation.
    • To provide a physical interpretation of the derived communication modes.

    Main Methods:

    • Derivation of an exact analytical method for finding spatial channels and connection strengths.
    • Calculation of the sum of squared connection strengths using a volume integral.
