Funneling acoustic waves through largely mismatched channels is of fundamental importance to tailor and transmit sound for a variety applications. In electromagnetics, zero-permittivity metamaterials have been used enhance the coupling energy in out ultranarrow channels, based on phenomenon known as supercoupling. These metamaterial can support total transmission complete phase uniformity, independent channel length, despite being geometrically with their input output ports. field acoustics,...

Materials with properties that can be described by a near-zero index of refraction have received significant attention in the fields electromagnetics, optics, and acoustics, due to their extraordinary capabilities wave manipulation. It was recently demonstrated theoretically experimentally acoustic waves could manifest near-zero-index propagation based on effective compressibility waveguide channel approaching zero. In turn, this allows tunneling nearly infinite wavelength (or equivalently,...

Epsilon-near-zero supercoupling is a widely-researched topic in electromagnetics. This phenomenon takes advantage of media with near-zero dielectric permittivity to build waveguide coupling channels which can, principle, support unitary transmission and complete phase uniformity, independent the length height channel. In this effort, we present possibility that an analogous, extraordinary coupled-mode exists acoustics, call compressibility-near-zero (CNZ) supercoupling. Prior works have...

Materials with properties which can be described by a near-zero index have received much attention in the fields of microwave electromagnetics, optics, and acoustics, due to their extraordinary capabilities wave manipulation. It was recently demonstrated, theoretically experimentally, that acoustic media support near-zero-index propagation, effective compressibility waveguide channel approaches zero. In principle, this allows complete tunneling waves nearly infinite wavelength (or...

Simultaneous transmit and receive (STAR) systems have recently enabled sending receiving of radio-frequency (RF) signals at the same time frequency using a single antenna. This has led to commercialization efforts with promise doubling throughput traditional radio systems, including Wi-Fi future 5G cellular communications. Prior these advances, researchers in vibration control been developing self-sensing actuator also referred as sensoriactuators or sensorless systems. Inspired by...
