Publikováno v: Physical Review

The violation of charge conjugation (C) and parity (P) symmetries are a requirement for the observed dominance of matter over antimatter in the Universe. As an established effect of beyond the Standard Model physics, this could point towards addition

Effective-Medium Modeling of a Meanderline Metamaterial-Enhanced Resistive Wall Amplifier Circuit for Particle-in-Cell Simulations

Autor: Nader Behdad, Patrick Forbes, John H. Booske

Publikováno v: IEEE Transactions on Plasma Science. 49:2700-2708

Theory and simulations predict the metamaterial-enhanced resistive wall amplifier (MERWA) may offer improvements to megawatt-level high-power microwave (HPM) amplifiers in terms of combined bandwidth and gain rates. A low-power proof-of-concept test

Space Charge Wave Growth Via Coupling To Lossy Backward Circuit Wave: Two Wave Theory

Autor: John H. Booske, Nader Behdad, Patrick Forbes

Publikováno v: 2021 IEEE International Conference on Plasma Science (ICOPS).

With the focus on increasing instantaneous bandwidth capabilities of high-power microwave (HPM) devices, the Metamaterial Enhanced Resistive Wall Amplifier (MERWA) is being investigated for potential use as an HPM amplifier 1 , 2 , 3 . Rather than gr

Inductive Meandered Metal Line Metamaterial for Rectangular Waveguide Linings

Autor: John H. Booske, Nader Behdad, Patrick Forbes, Tyler Rowe

Publikováno v: IEEE Transactions on Plasma Science. 45:654-664

Metal-based epsilon negative metamaterials (MTMs) have been investigated for use as a waveguide liner to allow for an electromagnetic passband below the cutoff frequency of the empty waveguide. In this paper, we investigate both the theory and a prac

Extracting Effective Complex Permittivity Parameters of a Metamaterial-Lined Rectangular Waveguide for Metamaterial-Enhanced Resistive Wallamplifiers

Autor: Stephen R. Dennison, Patrick Forbes, Nader Behdad, John H. Booske

Publikováno v: 2018 IEEE International Conference on Plasma Science (ICOPS).

Conventional resistive wall amplifiers using naturally occurring dielectric materials provide wide bandwidth but weak gain 1. We have shown that theory and simulations predict that metamaterial-enhanced resistive wall amplifiers (MERWAs) are candidat

Material Selection For The Periodic Elements Of A Metamaterial-Enhanced Resistive Wall Amplifier

Autor: Patrick Forbes, Tyler Rowe, Nader Behdad, John H. Booske

Publikováno v: 2017 IEEE International Conference on Plasma Science (ICOPS).

Resistive wall amplifiers are wideband vacuum electron devices that suffer from low gain due to available resistive materials 1. Metamaterial-enhanced resistive wall amplifiers (MERWAs) have been demonstrated, theoretically, to be a candidate for wid

Inductive meandered line metamaterial for metamaterial-enhanced resistive wall amplifiers

Autor: Nader Behdad, John H. Booske, Tyler Rowe, Patrick Forbes

Publikováno v: 2017 Eighteenth International Vacuum Electronics Conference (IVEC).

The metamaterial-enhanced resistive wall amplifier (ME-RWA) has been demonstrated, through theory, to be a high gain wideband amplifier. This work presents the design and preliminary cold test results of a constructed ME-RWA. In this ME-RWA design, t

Development and impact analysis of 3-year-old child FE human model

Autor: Koizumi, T., Tsujiuchi, N., Taki, N., Patrick Forbes, Lange, R.

In a previous study, a 3-year old child FE human model was developed by scaling down an adult male FE human model. Scaling down was performed for body dimensions, joint characteristics, and material properties. The focus of this current study is biof
