A shear horizontal (SH) wave has the characteristic of complete reflection at the free edges of a substrate with a large dielectric constant. A conventional surface acoustic wave (SAW) resonator filter requires reflectors consisting of numerous grating fingers on both sides of interdigital transducers (IDTs). On the contrary, it is considered that small-sized and low loss resonator filters without reflectors consisting of grating fingers can be realized by exploiting this characteristic of the SH wave or the Bleustein-Gulyaev-Shimizu (BGS) wave.

- Mamoru Ikeura's research primarily focuses on the development of very small and low-loss resonator filters using shear horizontal (SH) waves, specifically examining the unique characteristic of complete reflection at the free edges of substrates with high dielectric constants.
- His work suggests that conventional surface acoustic wave (SAW) resonator filters, which rely on numerous grating fingers for reflection, can be replaced by a more efficient design utilizing SH waves, leading to potential advancements in filter technology.
- The findings indicate that resonator filters without the traditional reflective grating structures can be effectively realized, paving the way for innovations in miniaturized electronic devices and improved frequency control mechanisms.
