Values of the relative permittivity, dielectric loss and conductivity are given for various rabbit ocular tissues at frequencies in the range 10 MHz-10 GHz. The tissues measured were cornea, retina, choroid, iris, and the cortical and nuclear zones of the lens. The dielectric parameters were determined using the technique of multiple response time domain spectroscopy. For all tissues the water relaxation could be characterised by a Debye dispersion with a relaxation time longer than that of pure water, indicating that its dielectric behaviour was affected by the presence of the biological macromolecules.
给出了10兆赫兹至10吉赫兹频率范围内各种兔眼组织的相对电容率、介电损耗和电导率值。所测量的组织包括角膜、视网膜、脉络膜、虹膜以及晶状体的皮质区和核区。使用多响应时域光谱技术测定介电参数。对于所有组织，水弛豫都可以用德拜色散来表征，其弛豫时间比纯水的弛豫时间长，这表明其介电行为受到生物大分子存在的影响。
