| Research Abstract |
The nondestructive testing using the electromagnetic wave is discussed. These are divided roughly into the following four : (1) Examination of simultaneous estimation of position and radius of reinforcing bar and relative permittivity of concrete using commercially concrete radar, (2) Establishment of diagnostic approach of fresh concrete, (3) Detection of parallel reinforcing bars and two vertical reinforcing bars using genetic algorithm, (4) Inquiry of cave into concrete structure using FBTS method that is one of methods of inverse scattering problem.
