The 3ω-method is a technique used in the field of thermal conductivity measurement, particularly for thin films and materials with small geometries. This method is based on the principles of frequency-domain thermography and utilizes a periodically heated sensor to measure thermal properties. ### Basic Principles: - **Sensor Design**: The technique typically involves a thin metallic line or film, which acts as both a heater and a thermometer. This line is usually deposited onto the material whose thermal properties are to be measured.
