Universal sample holder for measuring the electromagnetic properties of a dielectric and/or magnetic material

A sample holder for measurements of dielectric and/or magnetic characteristics of a sample, the sample holder system comprising:

• a central core having a first distal end extending outwardly with a reference axis (x) from the central core and a second opposing distal end extending outwardly with the reference axis from the central core;
• a first lateral wall having an outer edge and an orifice that engages the central core such that the first distal end of the central core extends through the orifice of the first lateral wall;
• a second lateral wall having an outer edge and an orifice that engages the central core such that the second distal end of the central core extends through the orifice of the second lateral wall;
• a tubular external body surrounding coaxially with the reference axis (x), the central core, the first lateral wall and the second lateral wall, the outer edge of the first lateral wall and the outer edge of the second lateral wall engaging the tubular external body such that the tubular external body, the central core, the first lateral wall, and the second lateral wall define a sample cavity;
• a first leaktight set linking, in a gas-tight and/or liquid-tight manner, the first lateral wall to the central core and to the external body;
• a second leaktight set linking, in a gas-tight and/or liquid-tight manner, the second lateral wall to the central core and to the external body;
• wherein laterally the external body exhibits recesses where the lateral walls are received and clamped by a first clamping means of each leaktight set;
• said first clamping means of each leaktight set comprising a first fastener operative to exert a compressive force between the corresponding lateral wall and the tubular external body.
