THE USE OF EDDY CURRENTS TO DETECT SURFACE-BREAKING DEFECTS IS WELL ESTABLISHED, AND MUCH KNOWLEDGE HAS BEEN BUILT UP IN ANALYZING THESE SIGNALS. HOWEVER, THE THEORETICAL BASIS FOR THIS TECHNIQUE IS U ...

THE ABILITY TO SOLVE INVERSE PROBLEMS LIES AT THE HEART OF ELECTROMAGNETIC NONDESTRUCTIVE EVALUATION (NDE). THESE PROBLEMS ARE DIFFICULT TO SOLVE FOR TWO REASONS: THEY ARE MATHEMATICALLY ILLCONDITION ...

A SERIOUS LACK OF EFFICIENT COMPUTER AIDED DESIGN (CAD) PROCEDURES EXISTS FOR HIGH-PERFORMANCE MONOLITHIC MILLIMETER WAVE INTEGRATED CIRCUITS, THAT OPERATE BETWEEN 30 AND 100 GHZ. THIS IS DUE TO THE H ...

We propose to design an eddy-current probe testing station, built aronnd a PC running Interactive Systems Carp. UNIX (ISC UNIX). The testing station will provide a quantitative evaluation of eddy-curr ...

THERE IS A NEED TO DEVELOP SPECIAL PURPOSE ALGORITHMS FOR SOLVING ELECTROMAGNETIC COUPLING AND SCATTERING PROBLEMS, THAT WILL TAKE ADVANTAGE OF RECENT ADVANCES IN COMPUTER TECHNOLOGY. TO THAT END WE P ...

NEW TYPES OF ANISOTROPIC MATERAILS, SUCH AS COMPOSITES, CERAMICS, AND HONEYCOMB STRUCTURE, ARE FINDING INCREASINGLY IMPORTANT APPLICATIONS IN HIGH-FREQUENCY ELECTROMAGNETICS. THESE APPLICATIONS RANGE ...

PREVIOUS RESEARCH HAS SHOWN THAT RECURSION EQUATIONS PROVIDE AN EXCELLENT COMPUTER HARDWARE DESCRIPTION LANGUAGE (CHDL). CURRENTLY THIS APPROACH IS NOT PRACTICAL BECAUSE IT PRODUCES SIMULATORS THAT AR ...

COMPUTATIONALLY EFFICIENT INVERSION ALGORITHMS ARE NEEDED IN A VARIETY OF DISCIPLINES, SUCH AS MEDICAL IMAGING, NONDESTRUCTIVE EVALUATION, GEOPHYSICAL PROSPECTING, AND ROBOTIC VISION. THE RIGOROUS MAT ...
