Dr. Caleap's research interests cover various aspects of wave propagation in heterogeneous complex media, including composite materials and metamaterials; his work encompasses ultrasonic array imaging, nonlinear ultrasound, structural health monitoring with guided waves, multiple scattering and ultrasonic particle manipulation.

Dr. Caleap is currently exploiting the emerging possibility of designing fluid-particle mixtures or composite materials to form acoustic or elastic metamaterials for various applications including reconfigurable ultrasonic filters, ultrasonic meta-lenses for super-resolution imaging of tiny defects, vibration cloaking of sensitive components, and stealth applications for the military to security.  

Current activity involves: 

  • Assembly of reconfigurable colloidal crystals and micro-particle super-lattices due to a synergy of fundamental nanoscale forces (e.g. acoustic & magnetic radiation forces)
  • Acoustic, elastodynamic and electromagnetic metamaterials
  • Particle manipulation with ultrasound
  • Non-destructive evaluation and guided waves
  • Wave propagation in heterogeneous media
  • Linear and non-linear ultrasonics
  • Super-resolution imaging
  • Acoustic quasicrystals


Dr. Mihai Caleap is the lead researcher in multifunctional soft acoustic metamaterials and novel colloidal microstructures at the University of Bristol. He earned a Bachelor’s Degree in Mathematics and Physics, as well as a Master’s Degree in Engineering Physics. Dr. Caleap obtained obtained his PhD in Mechanical Engineering in 2009 from the Physical Acoustics Group at Université de Bordeaux, France and subsequently briefly worked there as a Teaching and Research Assistant. From July 2009 to the present he worked as an academic in the Department of Mechanical Engineering at the University of Bristol.
