The minnaert bubble: an acoustic approach

WebOct 6, 2024 · Minnaert resonance, where a gas bubble suspended in a liquid resonates at its natural frequency, is a prominent example of a naturally occurring subwavelength resonator in undersea environments [1]. ... Recent research in acoustic metamaterials, which often rely on subwavelength resonances in structured lattices [2-4], has led to breakthroughs ... WebMay 1, 2012 · The function minnaert_freq calculates the approximate natural oscillation frequency (sometimes mistakenly referred to as the Minnaert resonance) of a gas bubble. The other functions, minnaert_rad and minnaert_vol return the radius or volume of a bubble given its natural resonance frequency.
