“…There are some examples in literature [21][22][23][24][25] related to numerical predictions and estimations of dielectric parameters of the tissue mimicking composites. Composite material that we propose consists of two components and is homogeneous with respect to the observed frequencies (Ca-alg spheres are much smaller than the wavelength).…”

Abstract-We present a new composite material containing calcium alginate microspheres incorporated into an epoxy matrix. The new material is mechanically stable and does not degrade over time. Its dielectric properties are extracted by model calculations and compared to the properties of some selected human tissues. Good agreement is observed, which identifies the proposed composite material as a good candidate for the use as a phantom material. The presented material is a two component composite and it is shown how its effective properties can be predicted by using appropriate mixing formulas.

“…Phantoms have been developed to mimic the dielectric properties of tissues in the microwave range. Formulae for various phantoms of different tissue types, generally specific to a discrete frequency, are available in the literature (Chou et al 1984, Hartsgrove et al 1987, Robinson et al 1991, Stauffer et al 2003. These phantoms are often used in place of real tissue when measuring the electromagnetic (EM) field distribution or the SAR (W kg −1 ) (EM power absorbed by the medium per unit mass) around an antenna or an array of antennas.…”

Phantoms are often used to simulate tissue during the development, testing and calibration of medical devices. In order to infer the specific absorption rate (SAR) and resistive heating in phantoms from temperature measurements, the specific heat capacity and density of the phantom are needed. Stauffer et al (2003 Int. J. Hyperth. 19 89-101) developed several phantoms that mimic dielectric properties of liver tissue at 915 MHz. However, thermal properties of the phantoms were not presented. We have measured specific heat capacities and densities for these phantoms. We also present dielectric properties for these phantoms measured from 0.7 to 20 GHz, including 2.45 GHz-a commonly used frequency for microwave hyperthermia and ablation.
