ADVANCED ELECTROMAGNETICS DIELECTRIC MATERIAL

AES/AEPF SERIES

1.0 INTRODUCTION

Advanced ElectroMagnetics, Inc., has developed a series of dielectric foams

providing a 1ossy medium to microwave energy. The AES Series materials are

ideally suited for electronic enclosures, radar systems and for other component

applications where low levels of RF absorption is desired. The AEPF version of

this material is used in anechoic chambers for treatment to wall to wall, or ceiling to

wall intersections.

This material provides additional lossy foam in areas and is used instead of miter

cut materials. The AES/AEPF materials are highly fire retardant and can be

provided in standard sheet sizes or in custom fabricated shapes. The following

specification describes the properties of the AES Series lossy dielectric slab

materials.

AEMI TECHNICAL BULLETIN AES/AEPF SERIES 3.0 MECHANICAL PROPERTIES 3.1 Thickness The AES Series material can be provided in any thickness up to 4". Thicker materials are glued with a non-f1ammable adhesive. The tolerances that can be achieved in cutting are typically plus or minus 1/16". Upon request, closer tolerances can be achieved with the use of additional tooling. 3.2 Planar Dimensions The AES Series material is provided in standard 24” x 24” sheets. Larger sheets are available up to 30” x 48” 3.

Special requirements for thickness and insertion loss can be provided on request. Similarly, data on dielectric constant can be provided for specific versions of this material. The permittivity of the different versions of this material will vary. 5.
