Angular Spectrum Method: A Comprehensive Overview

Introduction to Angular Spectrum Method

The Angular Spectrum Method is a technique used to model the propagation of a wave field. This method involves expanding a complex wave field into a summation of an infinite number of plane waves, all of the same frequency but different directions. Its roots are found in Fourier optics, but it has been widely applied in the field of ultrasound.

Modeling the Diffraction

The process of modeling the diffraction of a continuous wave (CW), monochromatic field involves several steps:

  1. Sampling the Complex Components: The real and imaginary components of a pressure field are sampled over a grid of points within a cross-sectional plane.
  2. 2D-FFT Transformation: The 2D Fourier transform decomposes the field into a 2D “angular spectrum” of component plane waves, each traveling in a unique direction.
  3. Multiplying by Propagation Term: Each point in the 2D-FFT is multiplied by a propagation term, accounting for the phase change that each plane wave will undergo.
  4. 2D-IFFT Transformation: The inverse Fourier transform yields the field over the prediction plane.

Extending the Model

In addition to predicting diffraction effects, the model has been extended to apply to non-monochromatic cases and include effects of attenuation, refraction, dispersion, and nonlinear effects of finite amplitude acoustic propagation.


  • Backward Propagation: Analyzing surface vibration patterns of acoustic radiators like ultrasonic transducers.
  • Forward Propagation: Predicting the influence of inhomogeneous, nonlinear media on acoustic transducer performance.

Key Insights and Thought-Provoking Questions

  1. Infinite Possibilities: How does the Angular Spectrum Method’s ability to break down a wave into infinite plane waves contribute to its accuracy in modeling wave propagation?
  2. Beyond Diffraction: What are the implications of extending the model to include nonlinear effects and other complex phenomena?
  3. Real-world Applications: How has this method revolutionized the field of ultrasound and what other fields could benefit from its application?

Conclusion: Embracing the Wave of Knowledge

The Angular Spectrum Method is a profound technique that transcends the boundaries of wave modeling. By embracing the complexity of waves and breaking them down into their fundamental components, it offers a gateway to understanding the very fabric of sound and light. 🌟💖
