“…The frequency dependence of the permittivity of various mammalian tumor tissues has been reported by several investigators. [Fricke and Morse, 1926;Bottomley and Andrew, 1978;Singh et al, 1979;Rogers et al, 1983;Schepps and Foster, 1980;Chaudhary et al, 1984;Zywietz et al, 1986;Smith et al, 1986;Surowiec et al, 19871. However, data at frequencies below 50 MHz are limited. To the best of our knowledge, only three studies have been reported on the dielectric properties of excised tumor tissues at low radiofrequencies [Bottomley and Andrew, 1978;Smith et al, 1986;Surowiec et al, 19873.…”
