This study focuses on optimizing the geometry of a reflector with the intent to maximize the amount of energy returned for a given wave guide mode. Past studies have focused on using Finite Element and Boundary Element techniques to determine the amount of energy reflected from a defect with a certain shape and size. Typically the artifacts explored are cracks, welds, notches, corrosion, etc. The Boundary Element technique is again used to predict the reflected energy from a reflector in order to determine what geometry gives the best reflection potential. The reflector in this case is attached to the existing structure so as not to harm structural integrity or interfere with the functions of the main structure. The potential use of such a reflector is discussed along with results from work in progress. © 2000 American Institute of Physics.

    Landfast ice is sea ice that forms and remains fixed along a coast, where it is either attached to the shore or held between shoals or grounded icebergs. The current generation of sea ice models is not capable of reproducing certain aspects of landfast ice behavior, for example the persistence...
