Electromagnetic Compatibility Society
Dear members of Boston EMC Compliance community,
Please, mark your calendars – on September 28 there will be an EMI/EMC Summit 2022, hosted by NTS and IEEE EMC Society Boston Chapter. This will be a third all-day event of that type in the last few years.
The Included link will allow you to register. Please, consider the fact that the space is limited and register soon. The registration form includes the agenda and bio of the speakers.
This link is now operational. You should expect a confirmation email upon registration. Please, check your SPAM folder if the confirmation message is missing.
The event includes exhibition of relevant EMC products and services by a number of providers.
Here is the information on four presentations and one demo offered in agenda –
Jeff Viel presentations
Overview of MIL-STD-461G-
This one-hour session will cover basic principles for EMI/EMC testing, and the purpose of the MIL-STD-461 standard. A general overview of each test method and importance of test setup, equipment configuration and operation are discussed. This session will also highlight some of the most common product compliance issues encountered during MIL-STD-461G testing, and lend advice on how they are remedied.
Overview of RTCA DO160G–
This one-hour session will cover a general overview of each test electrical and EMI related method (sections 15 through 23 and section 25). Comparisons will be made to aircraft platform requirements defined in MIL-STD-461G test setup. This session will also highlight some of the most common product compliance issues encountered during DO160G testing, and lend advice on how they are remedied.
International standards comparison-
This one-hour session will compare and contrast the product compliance requirements across several industries in an effort to highlight changes in platform electromagnetic environments, and how these changes can lead to severe compliance risks for multifunctional products deployed across a variety of commercial and defense platforms.

Basic Concepts of Antenna Characterization and Applications for EMC Measurements
There are some practical considerations for antennas used for EMC measurements; for example, EMC antennas are typically extremely broadband and low gain. At below 1 GHz, these antennas are used over a perfect electrical conductor (PEC) ground plane. This presentation provides an introduction and discussion of the antenna fundamental parameters from an application point of view, especially on how these antenna parameters are characterized and applied in EMC applications. We will review the definition of Antenna Factor (AF), its relationship to antenna gains, and mismatch losses. We will also look at other parameters often used in EMC applications, such as antenna balance, phase center, and site attenuation. A brief introduction to EMC antenna calibration methods will be provided, including a reference to dipole-like antennas, which are ubiquitous for EMC measurements below 1 GHz. Finally, we will discuss how these antenna parameters, such as the free-space antenna factors, are impacted by the presence of the conducting ground plane.

Cylindrical Mode Filtered SVSWR: A New ANSC C63® Method Proposed for EMC Site Validation from 18 GHz to 40 GHz” and a Live Demonstration
This presentation will introduce the new method of EMC site validation for high frequency range 18-40GHz, based on use of Cylindrical Mode Filtered SVSWR (CMF SVSWR). This CMF SVSWR provides a more comprehensive evaluation of EMC chamber quiet zone, and can be readily measured without any special positioning fixtures. This new measurement technique is under consideration for the new draft standard ANSI C63.25.3 in development by the ANSC C63 committee for EMC test sites from 18 GHz to 40 GHz.
Following the presentation will be a live demo in the NTS chamber – Cylindrical Mode Filtered SVSWR – A New ANSC C63.25.3 Method Proposed for EMC Site Validation from 18 GHz to 40 GHz” a live demonstration by Yibo Wang
We look forward to seeing many members of our community at the event,
