Wave propagation simulator

Simulates the propagation of waves from multiple transmitting elements.

Package status

Installation

Until this package gets registered, open the Julia environment from inside the package folder:

julia --project=.

Usage

using WaveSim

# Define simulation parameters (use many default values, see the WaveSimParameters struct).
sim_params = WaveSimParameters(
    focus_depth = 0.03,  # [m]
    steer_angle = 10.0,  # [deg]
    aperture_size = 0.02,  # [m]
);

# Compute focusing delay for the elements of the phased array.
trans_delays = WaveSim.delays_from_focus_and_steer(sim_params);

# (optional) Compute optimized "best" spatial and temporal parameters.
sim_params = WaveSim.autores(sim_params, trans_delays)

# Run the simulation.
images = WaveSim.wavesim(trans_delays, sim_params);
beam_energy_map, transmit_time_map, peak_to_peak_time_delta_map = WaveSim.beam_energy_map_and_transmit_time_map(images, sim_params);

# Display results.
include("src/view.jl")
imshowall(images, beam_energy_map, transmit_time_map, peak_to_peak_time_delta_map, sim_params);

# Save results.
include("src/save.jl")
saveall(images, beam_energy_map, transmit_time_map, peak_to_peak_time_delta_map, sim_params, "images")

Tips

Parallelization

The code supports multi-threading, make use of it by starting Julia with multiple threads: julia --threads 4 --project=.
