AndTech Inc. (Headquarters: Kawasaki City, Kanagawa Prefecture; President & CEO: Masao Suyama; hereinafter 'AndTech') will hold a Zoom lecture series for R&D support, titled 'Acoustic Metamaterials ~Basics and Applications of Next-Generation Sound Insulation Technology Using Negative Properties~' with leading experts.
Acoustic metamaterials are materials that exhibit unique properties such as negative permittivity and negative refractive index by periodically arranging structures with periods shorter than the target sound waves, enabling unprecedented wave control. This lecture will first organize the fundamental properties of sound and the evaluation and design of sound insulation materials, then systematically explain the concept and characteristics of acoustic metamaterials, with a particular focus on their application to sound insulation materials centered around Locally Resonant structures, explained in an easy-to-understand manner.
This course is scheduled to commence on Friday, May 29, 2026.

[Lecture Rationale]
Metamaterials are materials in which structural elements are periodically arranged with periods shorter than the target waves. They exhibit negative properties such as negative permittivity and negative refractive index in specific frequency bands, enabling wave control that cannot be achieved with conventional materials and exhibiting unique physical phenomena, thus attracting attention in recent years. Acoustic metamaterials are materials that apply this concept to sound waves.
This lecture will first outline the fundamental properties of sound and organize the concepts of performance evaluation and design of sound insulation materials. Then, it will explain the basics of acoustic metamaterials, and focusing on Locally Resonant (LR) type acoustic metamaterials, it will introduce their application to sound insulation materials and their characteristics in an easy-to-understand manner.
