974. Reflection and Transmission Properties of a Metafilm with Application to a Controllable Surface Composed of Resonant Particles
Topic: Electromagnetics
Published: 11/1/2005
Authors: Christopher L Holloway, Mohamed Mohamed, Edward Kuester
Abstract: In recent work, we derived generalized sheet transition conditions (GSTCs) for the average electromagnetic fields across a metafilm, which, when properly designed, can have certain desired reflection and transmission properties. A metafilm is the two ...

975. Relative Permittivity Measurement of Rectangular Copper-Laminated Substrates Using the Full-Sheet Resonance Technique
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5062
Topic: Electromagnetics
Published: 4/1/1997
Author: R L Lewis

976. Relaxation Times for Magnetization Reversal in a High Coercivity Magnetic Thin Film
Topic: Electromagnetics
Published: 3/17/1999
Authors: Thomas J Silva, Anthony B Kos, N D Rizzo
Abstract: We used a magneto-optical Kerr effect microscope to measure 180° magnetization reversal in a high coercivity CoCr10Ta4 thin film subjected to nanosecond field pulses. Exponential magnetization decay occurs for pulse duration tp<10 ns followed by log ...

977. Remanent-magnetization reversal in nickel-manganese alloys
Topic: Electromagnetics
Published: 10/1/1978
Authors: Ronald B Goldfarb, T. Satoh, Carl E. Patton
Abstract: Weakly ordered nickel-manganese alloys, field cooled to 4 K, exhibit a reversal in remanent magnetization upon warming. The reversal is dependent on the state of atomic order the cooling field. A local environment model and Mn-rich aggregates, which ...

978. Remote, Near-Field Measurement of Large Antennas
Topic: Electromagnetics
Published: 8/17/2002
Authors: Ronald Curtis Wittmann, Michael H Francis
Abstract: It is difficult to characterize many antenna systems in a laboratory environment. Size is the major consideration, but an increasing number of sophisticated antennas are being placed at remote sites where they are simply inaccessible. Of particular c ...

979. Repeatability Study of Commercial Harmonic Phase Standards Measured by a Nonlinear Vector Network Analyzer
Topic: Electromagnetics
Published: 12/5/2003
Authors: Jeffrey A Jargon, Donald C. DeGroot, Vecchia Dominic
Abstract: In this paper, we present the first published repeatability study of commercial harmonic phase standards (HPS) measured by a nonlinear vector network analyzer. Specifically, we measure two harmonic phase standards, one of which is specified to 20 GHz ...

980. Representation of Acoustic Waves in Unbounded Domains
Topic: Electromagnetics
Published: 1/1/2005
Authors: Bradley K Alpert, Y Chen
Abstract: Compact, time-harmonic, acoustic sources produce waves that decay too slowly to be square-integrable on a line away from the sources. We introduce an inner product, arising directly from Green s second theorem, to form a Hilbert space of these wav ...
