Resonance Properties of Leaky SAW Harmonics on Bonded Dissimilar-Material Structures

Autor: Ami Tezuka, Shoji Kakio, Masashi Suzuki, Shiori Asakawa, Jun Mizuno

Publikováno v: 2020 IEEE International Ultrasonics Symposium (IUS).

The propagation and resonance properties of leaky surface acoustic wave (LSAW) harmonics of a bonded dissimilar-material structure, such as LiTaO3(LT)/quartz and LiNbO3 (LN)/quartz, were investigated theoretically and experimentally. Using a finite e

Autor: Hiroaki Yokota, Kazuhito Kishida, Shoji Kakio, Shiori Asakawa, Jun Mizuno, Hiroyuki Kuwae, Masashi Suzuki, Toshifumi Yonai, Ami Tezuka, Junki Hayashi

Publikováno v: 2019 IEEE International Ultrasonics Symposium (IUS).

To obtain bonded structure with a low residual stress and a low attenuation for longitudinal leaky surface acoustic waves (LLSAWs), the propagation and resonance properties of an LLSAW on an amorphous layer inserted between LiNbO3 (LN) thin plate and

Study of Low-residual Stress Amorphous Film Deposition Method for LiTaO3/Quartz or LiNbO3/Quartz Bonding toward 5G Surface Acoustic Wave Devices

Autor: Kosuke Yamada, Hiroyuki Kuwae, Shoji Kakio, Jun Mizuno, Ami Tezuka, Shuichi Shoji

Publikováno v: 2019 International Conference on Electronics Packaging (ICEP).

LiTaO 3 (LT) or LiNbO 3 (LN)/Quartz bonded substrates with an amorphous intermediate layer were proposed to achieve both a large surface acoustic wave (SAW) velocity and a smaller temperature coefficient of frequency. Residual stress reduction of the

Enhancement of leaky surface acoustic wave harmonics excitation using bonded dissimilar-material structures

Autor: Ami Tezuka, Jun Mizuno, Shiori Asakawa, Shoji Kakio, Masashi Suzuki

Publikováno v: Japanese Journal of Applied Physics. 60:SDDC07

The enhancement of high-order surface acoustic wave (SAW) harmonics by increasing the metallization ratio was theoretically and experimentally investigated in high-performance bonded dissimilar-material structures. The simulation using a finite eleme
