Space-time (ST) wave packets are propagation-invariant pulsed optical beams that travel freely in dielectrics at a tunable group velocity without diffraction or dispersion. Because ST wave packets maintain these characteristics even when only one transverse dimension is considered, they can realize surface-bound waves (e.g., surface plasmon polaritons at a metal-dielectric interface, which we call ST-SPPs) that have the same unique characteristics as their freely propagating counterparts. However, because the spatiotemporal spectral structure of ST-SPPs is key to their propagation invariance on the metal surface, their excitation methodology must be considered carefully. Using finite-difference time-domain simulations, we show that an appropriately synthesized ST wave packet in free space can be coupled to an ST-SPP via a single nanoscale slit inscribed in the metal surface. Our calculations confirm that this excitation methodology yields surface-bound ST-SPPs that are localized in all dimensions (and can thus be considered as plasmonic “bullets”), which travel rigidly at the metal-dielectric interface without diffraction or dispersion at a tunable group velocity.
时空（ST）波包是一种传播不变的脉冲光束，它能在电介质中以可调的群速度自由传播，而不会产生衍射或色散。由于 ST 波包即使只考虑一个横向维度也能保持这些特性，因此它们可以实现表面束缚波（例如金属-电介质界面上的表面等离子体极化子，我们称之为 ST-SPPs），这些波具有与自由传播波相同的独特特性。然而，由于 ST-SPPs 的时空光谱结构是其在金属表面传播不变性的关键，因此必须仔细考虑其激发方法。通过有限差分时域模拟，我们发现自由空间中适当合成的 ST 波包可以通过刻在金属表面的单个纳米级狭缝耦合到 ST-SPP 上。我们的计算证实，这种激发方法能产生表面束缚的 ST-SPP，它们在所有维度上都是局部的（因此可被视为等离子 "子弹"），在金属-电介质界面上以可调的群速度刚性传播，没有衍射或色散。

We present a fully coherent, analytic model of the backscattering intensity in all HH, HV, VH, and VV channels, for the volume scattering of radiation from a layer of finite thickness, such as a vegetation layer over bare soil. We aim for a simple, not numerically intensive, model that could be used either as a forward model in a Bayesian estimation scheme, or else as a preliminary means to identify key features of a concrete problem, for its further analysis by more sophisticated theoretical and numerical approaches.
