Bibliography - Lossy Filters
1999-01-01
CURRENT
AIR1500
The following bibliography on lossy filters for use on electrical and electronic systems was prepared by the Lossy Filter Subcommittee AE-4C.2 of the Society of Automotive Engineers. The bibliography is in chronological sequence and is oriented toward the use of lossy materials to attenuate radio frequency noise on transmission lines.

Emc Antennas and Antenna Factors: How to Use Them
1999-01-01
CURRENT
AIR1509
This AIR discusses the use and application of EMC antennas and antenna factors. The relationships between antenna gain, antenna factor, power density (W/m2), and field strength (V/m) are discussed. Some examples of their use are given. Illustrations of commercially available EMC antennas commonly used in performing EMI measurements are included. In addition to the illustrations, the antenna factors, frequency ranges, typical uses (applications), and the manufacturers of these antennas are also listed.

ELECTROMAGNETIC COMPATIBILITY ON GAS TURBINE ENGINES FOR AIRCRAFT PROPULSION
2008-08-25
HISTORICAL
AIR1423
The purpose of this AIR is to acquaint the aerospace industry with problems in attaining electromagnetic compatibility on gas turbine engines, particularly as used in aircraft. It is also the purpose of this AIR to present guidelines for the application of EMC controls to the engine, to its components which of necessity must operate in very hostile environments and to its interface with the aircraft.

Coaxial Test Procedure to Measure the RF Shielding Characteristics of EMI Gasket Materials
2006-04-20
HISTORICAL
ARP1705A
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI gasket materials and EMI gaskets against various joint surfaces. The procedure is also used to test the reliability of the gasketed joint combinations after being subjected to hostile environments.

In-House Verification of EMI Test Equipment
2015-12-13
HISTORICAL
AIR6236
This AIR provides guidance to the EMI test facility on how to check performance of the following types of EMI test equipment: Current probe Line Impedance Stabilization Network (LISN) Directional coupler Attenuator Cable loss Low noise preamplifier Rod antenna base Passive antennas All performance checks can be performed without software. A computer may be required to generate an electronic or hard copy of data. This is not to say that custom software might not be helpful; just that the procedures documented herein specifically eschew the necessity of automated operation.

Recommended Insertion Loss Test Methods for EMI Power Line Filters
2004-08-18
HISTORICAL
ARP4244
This document presents standard methods to evaluate the common mode and differential mode insertion loss of passive electromagnetic interference power line filters from 10 kHz through 10 GHz. Insertion loss test methods for both quality assurance and performance prediction purposes are described. The performance prediction tests are selected to more closely approximate operating impedances. They are not intended to be inclusive or to represent worst case conditions. However, the methodology of this document can be used to determine the performance in an arbitrary impedance circuit.
