Description

technical field [0001] The invention belongs to the field of engineering geophysical exploration and detection, and in particular relates to a cement-based electromagnetic imaging composite material, a preparation method and an application thereof. Background technique [0002] Ground-penetrating radar is an important detection method in engineering geophysical prospecting and engineering quality inspection. The detection steps of ground-penetrating radar are generally as follows. , when the electromagnetic wave encounters a medium with different relative permittivity in the formation, the electromagnetic wave will be refracted and reflected on the surface of the medium, and then the reflected wave signal received by the receiving antenna of the ground penetrating radar will be analyzed to detect the target The depth, properties and structure of the medium are described. [0003] In the detection process, the dielectric constant of different media in the formation is the ke...
