A contactless method of generating ultrasonic Rayleigh waves at MHz frequencies in metals using the electromagnetic generation technique is described. The method requires the use of photographic printed circuit techniques for the production of the meander coil transducers. Excellent efficiency is achieved and insertion losses are as low as 78 dB in aluminum with an external magnetic field of 5 kG and a frequency of 4.75 MHz.
