Microwave propagation is adversely affected by evaporation duct, which can occur as often as 85% of the time in the sea of the world. Evaporation duct propagation is the abnormal bending and… (More)

The boundary element method is used to calculate the acoustic radiated field of a complicated conformal array of underwater acoustic projecting transducers. At first, the fundamental theory of the… (More)

The boundary element theory together with optimization method is used to calculate the vibration velocity weighting vector of a complicated conformal array of underwater acoustic projecting… (More)

In this paper, a fast and accurate method is presented that accounts for polarization and Gaussian rough surface effects over the sea for evaporation ducting conditions using the split step Fourier… (More)
