This document provides an overview of Head Tissue Simulating Liquids (HTSL) manufactured by SPEAG, designed for Specific Absorption Rate (SAR) testing. These liquids are crucial for accurately simulating the dielectric properties of human head tissue during electromagnetic field exposure assessments. The liquids are available in various formulations to cover a wide range of frequencies, ensuring compliance with international standards such as IEEE 1528, IEC 62209-1, IEC 62209-2, and FCC KDB 865664.
The document details narrow-band and broad-band solutions, each with specific test frequencies and main ingredients. Narrow-band solutions, like HSL300V2 and HSL450V2, are primarily composed of water and sugar, while broad-band solutions, such as HBBL1350-1850V3 and HBBL1900-3800V3, utilize water and Tween. The document also includes a material test report for HBBL600-10000V6, showcasing the measured dielectric parameters and their compliance with target values. This information is essential for researchers and engineers involved in SAR testing and regulatory compliance.
