Abstract
An acoustic transducer system for ultrasonic imaging may include an array of sub-wavelength ultrasonic transducer elements; at least one electromagnetically resonant element with an electromagnetic resonance within the electromagnetic frequency band coupled to each of the sub-wavelength ultrasonic transducer elements; at least one electromagnetically resonant element with an electromagnetic resonance within the electromagnetic frequency band coupled to each of the sub wavelength ultrasonic transducer elements; an electromagnetic transmission module configured to modify one or more characteristics of transmitted electromagnetic energy to effectuate an acoustic emission by the array of sub-wavelength transducer elements according to an acoustic transmission pattern corresponding to the respective electromagnetic resonance characteristics of at least some of the electromagnetically resonant elements coupled to the sub-wavelength ultrasonic transducer elements; and a common port configured to facilitate electromagnetic communication with each of the electromagnetically resonant elements coupled to the sub-wavelength transducer elements.
