Research
Prof. Sugino's research focuses on controlling and leveraging sound and vibration for a wide range of engineering applications, such as aerospace structures, non-destructive evaluation, and biomedical ultrasound. In particular, he uses metamaterials, architected structures with small-scale repeated units, to obtain mechanical properties not achievable in conventional materials, such as one-way vibration transmission. His work is highly interdisciplinary, integrating active components, feedback circuitry, and electrical networks to manipulate the flow of elastic and acoustic waves.
