Abstract
Bats use echolocation to navigate their environment, to localize and identify prey. Researchers have proposed ultrasonic biomimetic systems that make use of the way bats echolocate. EMFi is a new material, which has good properties for air. We used this material to construct an ultrasound emitter capable to work in a similar way as bat’s emitter. We did measurements in order to study the far field directivity pattern for an EMFi hemi-cylindrical array with four strips. Experimental studies of the directivity emission in far field for this type of transducer highlighted the capabilities of this emitter.
