Abstract :
The design of a SC-cut resonator for which the C-mode has a lower resistance than the B-mode (typical ratio 1.5) is presented. This result is obtained by using an antisymmetric anharmonic mode with a particular geometry and connection of the electrodes. Experimental results (motional resistance, thermal behaviour) are given for a third overtone, 10 MHz, resonator
