Title:
DESIGN SUPPORT METHOD AND DESIGN SUPPORT APPARATUS FOR ANTENNA NEAR LIVING BODY
Document Type and Number:
Japanese Patent JP2014212953
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to perform accurate analysis even when the size of a living body is larger than a wavelength by using a calculation method by combining an impedance method with a moment method.SOLUTION: A design support method for an antenna near a living body by combining an impedance method with a moment method is used for calculating an electromagnetic field characteristic of the antenna near the living body by: calculating an electromagnetic field generated in the case that unit current flows through a divided segment of the antenna in the moment method; calculating an electric field inside the living body caused by the electromagnetic field as an incident wave, by the impedance method; calculating a secondary scattering field inside the living body caused by the electric field inside the living body; calculating an electric field inside the living body generated in the case of adding the secondary scattering field to the incident wave, by the impedance method; calculating an outer-living body scattering electric field generated by the inner-living body electric field; and calculating influence of the outer-living body scattering electric field on the antenna.
