Phantoms mimicking electromagnetic properties of biological tissues are widely used in evaluation of electromagnetic field distribution in human body. In this paper, low-viscous, optically transparent liquids that mimic muscle tissue, are designed and characterized. Various mixing ratios of de-ionized water and diethylene glycol butyl ether are examined in range of widely used biomedical frequencies. A recipe for 2.45 GHz is given, which provides less than 5.6% deviation from the reference. With help of curve fitting of the discrete measurement points, recipes for other parts of the body can be produced. For example, a recipe for the grey matter of the human brain is suggested, resulting in less than 4.7% deviation. An improved recipe for muscle tissue, where Triton X-100 is added, improves the target recipe to less than 1% deviation from the reference.
