Microwave Vision Group has introduced the SAM and Elliptical phantoms that are manufactured to precise specifications outlined in the 3D-CAD files set forth by industry standards. Each is delivered with a compliance certificate. They are designed for integration with MVG COMOSAR phantom tables.
In the world of wireless devices, understanding how our bodies absorb electromagnetic field (EMF) energy is paramount. The proximity to these devices directly influences the amount of energy our bodies absorb. This is where Specific Absorption Rate (SAR) measurements come into play. SAR measurements assess the rate at which the human body absorbs EMF energy from wireless devices, ensuring that products meet safety standards and pose no harm to users.
MVG SAR Phantoms, including the SAM and Elliptical phantoms, are at the forefront of simplifying and improving SAR measurements. These specialized tools emulate human tissues, enabling precise measurements and guaranteeing compliance with industry standards.
Compliance
As stipulated in the standards, the SAM (Specific Anthropomorphic Mannequin) and Elliptical phantoms are made of low-loss and low-permittivity material. The material is resistant to Glycol and offers high rigidity (composite material based on fiberglass). In the SAM phantom, the low-loss ear spacer provides spacing of 6 mm from the tissue boundary at the Ear Reference Point (ERP) within a tolerance of less than ± 0.2 mm. The Elliptical phantom has an elliptic shape, all as prescribed by the standards.
Easy and Precise Positioning
The SAM and Elliptical phantoms have been designed so that positioning of the Device Under Test (DUT) and probes can be done under repeatable and stable conditions. The SAM phantom provides 4 reference points:
- one on the top part of the phantom to position the tip of the probe correctly.
- one in the center of each of the phantom’s parts (right head/ERP, left head/LEP and flat part).
In addition, the outside shell of the SAM phantom includes a perpendicular cross-section (between the ear reference point and the mouth, as well as between the neck and the forehead). This cross-section is used as a reference to position the acoustic output of the device.
The Elliptical phantom provides one reference point on its top part to position the probe tip correctly.
