“…Clinton consulted TI to support development of compressive receivers and pulse compression radars using slanted IDTs [46][47][48]. He also consulted ASCOM Microsystems (later Advanced SAW Products, or ASP, and then Micronas) for development of radio frequency (RF) SAW devices for communications [54][55][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. Some stories in this period are given in the next section.…”

A brilliant super-star in the SAW community, Clinton Sylvester Hartmann passed away in Dallas, TX, on February 4, 2013, at the age of 68. This article reviews Clinton's professional career and achievements at first, and then a few stories between Clinton and me are given. The stories tell how deeply Clinton contributed to my career up and early achievements. They also show how Clinton motivated, trained, and directed one young engineer.

“…An obvious three-dimensional effect in SAW resonators is the use of transverse modes in transversely coupled SAW resonators filters [17][18][19][20][21]. Here the SAW propagates essentially in the X-Y saggital plane but is coupled transversely in the Z direction to another SAW propagating essentially in the same saggital plane.…”

Numerical results on the resonant frequencies and their frequency-temperature behavior in a three-dimensional surface acoustic wave (SAW) periodic structure are presented. These results are compared with those of the quartz SAW resonator . The 3-d fem models of SAW periodic structures are useful in the analyses of IDTs geometry and crystal cuts of SAW resonators which have power flows transverse to the SAW phase velocity. They are also useful for analyzing transversely coupled SAW resonators.Piezoelectric, Lagrangian equations for the frequencytemperature behavior of quartz are presented. Threedimensional finite element results for a half wavelength SAW periodic structure are compared with measured data from SAW resonator . The frequency characteristics of the fundamental SAW mode and its transverse overtones as a function of the electrode length W in the transverse direction are studied. Generally good results are obtained by the 3-d fem models when compared with measured values. Their frequency-temperature behavior are also studied and are reasonably well predicted by the 3-d SAW periodic structure. The 2-d fem models are shown to yield results consistent with the 3-d fem models.
