ANSYS Inc. (ANSYS) has filed a Request for Waiver of Section 1.1307 (b)(2) of the
Commission’s Rules to permit routine environmental evaluation for radio frequency (RF) exposure of
medical implant or body-worn transmitters authorized for use in the Medical Device
Radiocommunication (MedRadio) Service by finite element method (FEM) computational modeling.1
ANSYS is the developer and marketer of High Frequency Structure Simulator (HFSS), a FEM-based
software tool for simulation testing used by engineers, designers, and researchers in various industries.
Section 1.1307 (b)(2) requires routine environmental evaluation for radio frequency (RF)
exposure from equipment transmitting in the MedRadio Service prior to equipment certification, as
specified in Section 2.1093 by laboratory measurement techniques or finite difference time domain
(FDTD) computational modeling. ANSYS submits that FEM-based software is capable of simulating
fundamental physics on an equal basis with FDTD-based software, and thus should be permitted for
evaluating medical implant or body-worn transmitter compliance with the Commission’s RF exposure
rules. ANSYS notes that the IEEE International Committee for Electromagnetic Safety Technical
Committee 34 is developing recommended practices for using both FDTD and FEM for evaluating RF
safety of wireless communication devices, which will eventually be submitted to the IEEE Standards
Committee for consideration. Thus, ANSYS argues that waiving our rule to permit FEM-based
computational modeling to stimulate the specific absorption rate (SAR) of MedRadio devices would
expand the availability of engineering testing methodologies for medical device manufacturers, thereby
enabling manufacturers and researchers to negotiate lower costs for product development.
The Commission’s Office of Engineering and Technology (“OET”) is reviewing the Request for
Waiver. OET has concluded that in order to develop a complete record on the issues presented by this
request, it will treat this proceeding, for ex parte purposes, as a “permit-but-disclose” proceeding, in
accordance with Section 1.1200(a) of the Commission’s rules, and subject to the requirements under
Section 1.1206(b) of the rules.


1 See ANSYS Inc., Request for Waiver of 47 C.F.R. § 1.1307 (b)(2), filed August 2, 2010. The MedRadio
Service is governed by Part 95 of the Commission’s Rules.
