Phaseless spherical near-field antenna measurements for low and medium gain antennas [PDF]
Advances in Radio Science, 2010 The characterisation of antenna radiation patterns by measurements in the near-field and a following near-field far-field transformation require accurate amplitude and phase data. Especially at higher frequencies phase measurements are demanding in terms

On amplitudes and field redefinitions
Journal of High Energy PhysicsAbstract We derive an off-shell recursion relation for correlators that holds at all loop orders. This allows us to prove how generalized amplitudes transform under generic field redefinitions, starting from an assumed behavior of the one-particle-irreducible effective action.

Multiloop string amplitudes with -field and noncommutative QFT [PDF]
Nuclear Physics B, 2000 The multiloop amplitudes for the bosonic string in presence of a constant B-field are built by using the basic commutation relations for the open string zero modes and oscillators. The open string Green function on the annulus is obtained from the one loop scattering amplitude among N tachyons.

Computation of Amplitudes in the Discretized Approach to String Field Theory [PDF]
Physical Review Letters, 1988 An approach to Witten string field theory based on the discretization of the world sheet is adopted. We use it to calculate tree amplitudes with the formulation of the theory based on string functionals. The results are evaluated numerically and turn out to be very accurate, giving, for a string approximated by 600 points, values within 0.02% of the ...

The steady-state form of large-amplitude internal solitary waves
, 2010 A new numerical scheme for obtaining the steady-state form of an internal solitary wave of large amplitude is presented. A stratified inviscid two-dimensional fluid under the Boussinesq approximation flowing between horizontal rigid boundaries is ...

Coordinated ground-based and Cluster observations of large amplitude global magnetospheric oscillations during a fast solar wind speed interval [PDF]
, 2002 We present magnetospheric observations of very large amplitude global scale ULF waves, from 9 and 10 December 2000 when the upstream solar wind speed exceeded 600 km/s.

String scattering amplitudes and deformed cubic string field theory
Physics Letters B, 2018 We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge.
