The generation of ultrasonic waves by a remote way, inducing magnetic fields to magnetic nanoparticles, is an important scientific advance that has been demonstrated in other works. With this technique, it could be avoided some problems of conventional ultrasound related to attenuation. In this work, a glass tube waveguide to transmit 1 MHz ultrasound was studied in order to find an optimal length in which ultrasonic waves are transmitted with the minimum losses. The length of the waveguide is an important factor that modifies the transmission of a signal trough it; some optimal tube lengths can be used to obtain the best ultrasonic transmission with the proposed waveguide were found. |
