Second harmonic leakage suppression by notching [PDF]
1998 IEEE Ultrasonics Symposium. Proceedings (Cat. No. 98CH36102), 2002 Harmonic imaging offers better contrast resolution than conventional B-mode image. However, in ultrasonic array imaging system, the transmitting source contributes not only the fundamental harmonic but also the other harmonics. It is shown theoretically and experimentally that the interference of the transmitting-leaked second harmonic signal to the ...

Relativistic ionization-rescattering with tailored laser pulses [PDF]
, 2006 The interaction of relativistically strong tailored laser pulses with an atomic system is considered. Due to a special tailoring of the laser pulse, the suppression of the relativistic drift of the ionized electron and a dramatic enhancement of the ...

A study of harmonic spatial propagation along AC power lines of meshed power systems
IET Circuits, Devices and Systems, 2022 Severe harmonics propagation in power systems may result in increased power losses and equipment damages. In this paper, an elliptic formula is derived to analyse the harmonic spatial distribution not only at the substations but also along the power ...

A formula for charmonium suppression
, 2011 In this work a formula for charmonium suppression obtained by Matsui in 1989 is analytically generalized for the case of complex c-cbar potential described by a 3-dimensional and isotropic time-dependent harmonic oscillator (THO).

Orthogonality catastrophe and fractional exclusion statistics
, 2018 We show that the $N$-particle Sutherland model with inverse-square and harmonic interactions exhibits orthogonality catastrophe. For a fixed value of the harmonic coupling, the overlap of the $N$-body ground state wave functions with two different values
