On the Electromagnetic Propagation Paths and Wavefronts in the Vicinity of a Refractive Object

Maxwell's equations are transformed from a Cartesian geometry to a Riemannian geometry. A geodetic path in the Riemannian geometry is defined as the raypath on which the electromagnetic energy efficiently travels through the medium. Consistent with the spatial behavior of the Poynting vector, the metric tensor is required to be functionally...

Increasing the Strength of an Adhesive Joint: Geometry Optimization of Complex Joint Configurations for Implementation in Composite Micro Truss Structures

A FEM-based tool was developed for optimization of the geometry of an adhesive joint for implementation in a composite micro truss structure. A genetic algorithm was employed to optimize the adhesive fillet and adherend local end geometry towards a uniform state of strain in the adhesive layer. It was found that the peak maximum principal strain...
