Experiment results of a novel sub-bottom profiler using synthetic aperture technique

Current Science, 2022
Using Mills cross-configuration of multibeam sonar and synthetic aperture technique, a downward-looking synthetic aperture sonar (SAS), used for the sub-bottom profiler is presented here.

A Lightweight Planar Ultrawideband UHF Monopole Mills Cross Array for Ice Sounding

IEEE Antennas and Wireless Propagation Letters, 2020
An electrically large ultrawideband ultrahigh frequency (UHF) monopole antenna array has been designed to sound up to 3 km of ice and meet the logistical requirements of transportation to arctic regions.

The differential of all two-loop MHV amplitudes in $ \mathcal{N}=4 $ Yang-Mills theory [PDF]

, 2013
A bstractWe present an explicit analytic calculation of the differential of the planar n-particle, two-loop MHV scattering amplitude in $ \mathcal{N}=4 $ super Yang-Mills theory. The result is expressed only in terms of the polylogarithm functions Lik(−x)

Y-system for scattering amplitudes [PDF]

, 2010
We compute super Yang–Mills planar amplitudes at strong coupling by considering minimal surfaces in AdS5 space. The surfaces end on a null polygonal contour at the boundary of AdS.

Frequency-diverse microwave imaging using planar Mills-Cross cavity apertures.

Optics Express, 2016
We demonstrate a frequency diverse, multistatic microwave imaging system based on a set of transmit and receive, radiating, planar cavity apertures. The cavities consist of double-sided, copper-clad circuit boards, with a series of circular radiating ...

Existence of a New Instanton in Constrained Yang-Mills-Higgs Theory

, 1993
Our goal is to discover possible new 4-dimensional euclidean solutions (instantons) in fundamental SU(2) Yang-Mills-Higgs theory, with a constraint added to prevent collapse of the scale.

Realization of D4-Branes at Angles in Super Yang-Mills Theory

, 1997
An explicit solution in super Yang-Mills theory, which after T-duality describes two sets of D4-branes at angles, is constructed. The gauge configuration possesses 3/16 unbroken supersymmetry for the equal magnitudes of field strengths, and can be ...

Aspects of Duality and Confining Strings [PDF]

, 1999
We inspect the excitation energy spectrum of a confining string in terms of solitons in an effective field theory model. The spectrum can be characterized by a spectral function, and twisting and bending of the string is manifested by the invariance of ...

BPS Spectrum, Indices and Wall Crossing in N=4 Supersymmetric Yang-Mills Theories

, 2012
BPS states in N=4 supersymmetric SU(N) gauge theories in four dimensions can be represented as planar string networks with ends lying on D3-branes. We introduce several protected indices which capture information on the spectrum and various quantum ...

Singular Monopoles and Supersymmetric Gauge Theories in Three Dimensions [PDF]

, 1998
According to the proposal of Hanany and Witten, Coulomb branches of N=4 SU(n) gauge theories in three dimensions are isometric to moduli spaces of BPS monopoles.
