To compare the measured and the simulated radio frequency Bt distribution in cylindrical phantoms and in the head of healthy volunteers at 128 MHz. The experimental data were obtained with a 3 Tesla MRI research system equipped with a blrdcage coil. The simulated data were obtained with the Finite Difference Time Domain (FDTD) method of calculation for electromagnetics. MATERIAL AND METHODS the...

[1] Meteoroid head echoes are radar returns associated with scatter from the dense plasma surrounding meteoroids striking the Earth’s atmosphere. Such echoes are detected by high power, large aperture (HPLA) radars. Frequently such detections show large variations in signal strength that suggest constructive and destructive interference. Using the ARPA Long‐Range Tracking and Instrumentation Ra...

For computational physics simulations, code verification plays a major role in establishing the credibility of results by assessing correctness implementation underlying numerical methods. In electromagnetics, surface integral equations, such as method-of-moments magnetic-field equation, are frequently used to solve Maxwell's equations on surfaces electromagnetic scatterers. These yield many co...

This paper addresses the latest advancements in the application of computational electromagnetics and smart telemetry systems to the development of a retinal prosthesis to restore the sight in the blind. Numerical methods and models have been developed to a) accurately characterize the thermal increase in the human head and eye associated with the operation of the retinal prosthesis, b) determi...
