【Seminar】107/5/17 Vibration /Noise Reduction Using Metamaterials
演講時間：107/5/17（四）15:30-17:00
演講地點：國立清華大學工程一館107演講廳
演講者：國立成功大學工程科學系 陳蓉珊副教授
講題：Vibration /Noise Reduction Using Metamaterials
摘要：Over decades, periodic structures have been viewed as good candidates for vibration reduction or noise isolation. One typical example is phononic crystals consisting of periodically distributed inclusions in a matrix. Those crystals exhibiting the phenomenon of bandgaps can cause attenuation in wave amplitude. The wave filtering mechanism is attributed to the structural periodicity. Recently, there has been a rising interest in a new class of materials named locally resonant acoustic/elastic metamaterials. Those kinds of materials possess unusual physics properties that do not exist in the natural materials and have been proven useful in attenuating low-ferquency sound/vibration. By altering the geometric/physical properties of metamaterials, the desired bandgap can be easily obtained.
