A Perfectly Matched Layer (PML) is an artificial absorbing layer used in computational models to simulate the effect of an infinite domain, preventing reflections at the boundaries of a finite computational grid. It is crucial in wave propagation simulations, such as electromagnetic, acoustic, and seismic waves, to ensure accurate results by absorbing outgoing waves without reflection.

Computational models are abstract representations that use algorithms and mathematical formulations to simulate complex systems and predict their behavior under various conditions. They are essential tools in fields like physics, biology, and economics, providing insights that are often unattainable through traditional experimental methods alone.

Wave propagation simulations

Electromagnetic waves are oscillations of electric and magnetic fields that travel through space at the speed of light, encompassing a broad spectrum from radio waves to gamma rays. They do not require a medium to propagate and are fundamental to many technologies, including communication, imaging, and energy transfer.

Electromagnetic Waves

Acoustic waves are oscillations of pressure transmitted through a medium, such as air, water, or solid materials, and are perceived as sound when they reach the human ear. These waves are characterized by properties such as frequency, wavelength, and amplitude, which determine the pitch, speed, and loudness of the sound.

Acoustic Waves

Seismic waves are energy waves generated by the sudden breaking of rock within the earth or an explosion, and they are the primary means by which the energy from earthquakes is transmitted through the Earth. These waves are crucial for seismologists to study the internal structure of the Earth and to locate and measure the magnitude of earthquakes.
