Description
144MHz帯はアマチュア無線端末などで使用されている周波数帯であり、これらの端末は腰または胸に取り付けて使用される。したがって、比複素誘電率の目標値を全身の均一組織用標準として用いられている2/3筋肉用の値(比複素誘電率の実部46.06、虚部65.14)とした。
1450MHz帯は携帯電話などで使用されている周波数帯であり、これらの端末は頭部に接近させて使用される。したがって、比複素誘電率の目標値を頭部等価組織の値(比複素誘電率実部41.00、虚部14.90)とした。
イオン交換水53.82gに対して、45.51gのDGBE(ジエチレングリコールモノブチルエーテル)および0.67gの食塩を混合して、人体誘電率模擬液剤を形成した。
