PROBLEM TO BE SOLVED: To provide an undamageable and lightweight solid phantom by using synthetic resin as a base material, mixing in conductive fiber to impart a necessary dielectric constant in a solid phantom used to study the interaction of an electromagnetic wave and a living body. SOLUTION: Strongness, flexibility, that a packing material can be easily mixed in or the like can be cited as the requirements for resin used as a base material, but for example, silicon, urethane, polyethylene or the like are used as synthetic resin to satisfy these requirements. A conductive material is mixed in to increase a dielectric constant, or bubbles are mixed in to satisfy a demand value. Fiber by evaporating metal on an insulator such as glass fiber and metallic fiber are used as conductive fiber, but a mixing quantity of this conductive fiber is optimal in a range of 1/10 to 1/20 in the weight ratio to resin. A method to mix in beads containing gas abundantly or the like can be citted as a method to mix in bubbles. |
