The Inclusion-Based Boundary Element Method (iBEM) is an innovative numerical method for the study of the multi-physical and mechanical behaviour of composite materials, linear elasticity, potential flow or Stokes fluid dynamics. It combines the basic ideas of Eshelby's Equivalent Inclusion Method (EIM) in classic micromechanics and the Boundary Element Method (BEM) in computational mechanics.

The book starts by explaining the application and extension of the EIM from elastic problems to the Stokes fluid, and potential flow problems for a multiphase material system in the infinite domain. It also shows how switching the Green's function for infinite domain solutions to semi-infinite domain solutions allows this method to solve semi-infinite domain problems. A thorough examination of particle-particle interaction and particle-boundary interaction exposes the limitation of the classic micromechanics based on Eshelby's solution for one particle embedded in the infinite domain, and demonstrates the necessity to consider the particle interactions and boundary effects for a composite containing a fairly high volume fraction of the dispersed materials.

Starting by covering the fundamentals required to understand the method and going on to describe everything needed to apply it to a variety of practical contexts, this book is the ideal guide to this innovative numerical method for students, researchers, and engineers.

This book highlights reviews, perspectives, and original research that contribute to the advanced interdisciplinary studies of theories, technologies, and strategies on THz sensing, biophysics, communications, and bio-effect research. The terahertz (THz) frequency covers a spectrum important for applications such as body security, non-destructive matter sensing, bio-imaging, and bio-medicine. It overlaps with the characteristic fingerprints of molecular vibrations and rotations (e.g., proteins and DNA) and thus could resonantly interact with various bio-matters. The 2021 Nobel Prize in medicine was granted for the discovery of ion channels of temperature and pressure sensing. The frequency of THz makes it absorbable for bio-effect and modulation of bio-molecules, especially for ion channels. Besides, the high-speed modulation in terahertz is a holy grail for integrated photonics in high-capacity computations. This topic has raised widespread interest in fundamental science and applications for THz. The proceedings are suitable for researchers and students interested in interdisciplinary research at the intersection of electromagnetics, physics, and life sciences.
