HUMAN PHANTOM SHELL AND HUMAN PHANTOMS OF BRAIN TISSUE SKULL TISSUE AND MUSCLE TISSUE FOR ELECTROMAGNETIC WAVE ENVIRONMENTS ESTIMATION

摘要

The present invention overcomes the drawbacks of phantoms in liquid and quasi-liquid form, namely the measurement of specific absorption on the surface and reproducibility after a certain period of time, and a human phantom shell that can solve the air-gap problem in the phantom in solid form. It is also intended to provide a human phantom for each tissue having a dielectric constant and conductivity substantially similar to that of the brain, muscle and skull of human tissue at a particular frequency. The human body phantom shell of the present invention for this purpose is made of a composite material prepared by mixing a dielectric material and a conductor material with the shape memory polymer as a base material, and each human body phantom for brain, muscle, and skull tissue is a shape memory polymer material. Dielectric and conductor materials are added to the substrate, with appropriate compositions so as to have relative permittivity and conductivity substantially similar to tissues of the human body in the cell phone frequency band.
