The absorber used in anechoic and semi-anechoic chambers employed for emissions and
immunity testing of digital devices is examined. Using reflectivities obtained by the method of …

The interaction of electromagnetic waves with an array of absorbing wedges or pyramid
cones is studied in the low-frequency limit; ie, when the period of the array is small …

In this work, two kinds of auxetic composite foams of polyurethane (PU) with polydopamine
(PDA) and graphene (GR)(PU/PDA/GR) were prepared by dip-coating and ultrasonic …

With the phenomenal development of electromagnetic wave communication devices and
stealth technology, electromagnetic wave absorbing materials have been attracting attention …

We present the design, manufacturing technique, and characterization of a 3D-printed
broadband graded index millimeter wave absorber. The absorber is additively manufactured …

A proper model of RF absorber must be developed based on information such as absorber
reflectivity, in magnitude and phase, for various angles of incidence, and for parallel and …

Based on the theoretical model developed in Part I of this two-part paper, we present
numerical results for the plane-wave reflection coefficient from arrays of pyramid-cone …

For short-propagation paths, correctly representing reflections of electromagnetic energy
from surfaces is critical for accurate signal-level predictions. In this paper, the method of …

The evolution of the frequency-dependent absorption spectra for plastoferrites and carbon
black-filled ethylene butylacrylate copolymer composites subjected to a uniaxial tension is …

This issue's “Measurements Corner” article presents detailed descriptions of two novel
geometric optics methods for the analysis and design of anechoic chambers. The …
