Abstract[English]
A waveguide array is configured to convey ultrasonic soundwaves. The waveguide array includes a plurality of waveguide elements. Each of the waveguide elements defines a proximal end configured to receive the ultrasonic soundwaves produced by the transducer and a distal end opposing the proximal end. A cross-sectional width of each of the waveguide elements is less than a wavelength of the ultrasonic soundwaves. An inward area of the waveguide array at the proximal ends of the waveguide elements is greater than an outward area of the waveguide array at the distal ends of the waveguide elements.[French]
Un réseau de guides d'ondes est conçu pour transporter des ondes sonores ultrasonores. Le réseau de guides d'ondes comprend une pluralité d'éléments de guide d'ondes. Chacun des éléments de guide d'ondes définit une extrémité proximale conçue pour recevoir les ondes sonores ultrasonores produites par le transducteur et une extrémité distale opposée à l'extrémité proximale. Une largeur de section transversale de chacun des éléments de guide d'ondes est inférieure à une longueur d'onde des ondes sonores ultrasonores. Une zone intérieure du réseau de guides d'ondes au niveau des extrémités proximales des éléments de guide d'ondes est supérieure à une zone extérieure du réseau de guides d'ondes au niveau des extrémités distales des éléments de guide d'ondes.
