    Changing of an Airy pulse form due to re-reflections inside a dielectric layer
    (YSF, 2016) Kuryzheva, O. V.; Nerukh, A. G.
    A problem of Airy pulse transformation by a plane-parallel layer is considered. A problem formulation is equivalent to a case of permittivity sharp change in a dielectric layer at zero moment of time. It allows to use the resolvent method for solution of the Volterra integral equation describing this phenomenon. It is shown a virtual structure of a pulse field inside the layer. Influence of a number of pulse re-reflections from the layer boundaries on a form of a primary pulse is analyzed.

    Evolution of an Airy pulse energy flow induced by a dielectric plane boundary
    (CAOL, 2016) Kuryzheva, O. V.; Nerukh, A. G.
    Transformation of energy flows of an electromagnetic Airy pulse by a plane boundary of a dielectric is considered. It is shown that a problem formulation is equivalent to a case of a permittivity sharp change in a half space at zero moment of time. It allows to use the resolvent method for solution of the Volterra integral equation describing the phenomenon. Explicit expressions for transmitted and reflected pulses are obtained and energy flows are analyzed.

    Radiation of accelerating pulses with specified envelopes
    (ICATT, 2015) Nerukh, A. G.; Zolotariov, D. A.; Kuryzheva, O. V.
    A problem for radiation of time accelerating electromagnetic pulses is considered in paraxial approximation. It is shown that the pulse envelope moves in the time-spatial coordinates on the surface of a cylinder, the parabolic one for the pulse in the form of Airy function and for the hyperbolic one for Gaussian. Each of the pulse propagates in time with deceleration along the dominant propagation direction and drifts uniformly in the lateral direction stopping at infinity.
