We study the behavior of Goos-H$\ddot{\text{a}}$nchen shift (GHS) using $s$- and $p$-polarized partial coherent beam incident on three-dimensional (3D) Dirac semimetal. By studying the real part of permitivity of 3D Dirac semimetal, we identify the dielectric, epsilon near zero (ENZ) metamaterial, and metallic regions for the incident wavelength. Interestingly, for $s$- and $p$-polarized partial coherent beam, we get a completely different behavior of GHS in the reflected beam in the dielectric and metallic regions. Some factors such as spatial coherence, the wavelength and spatial width of the incident beam, temperature, and thickness of 3D Dirac semimetal are discussed in the influence of GHS. We can have negative and positive GH shifts in these three regions of Dirac semimetal for $s$- and $p$-polarized partial coherent beam.

我们研究Goos-H的行为$\ddot{\text{一种}}$nchen shift（GHS）使用 $s$-和 $p$偏振的部分相干光束入射到三维（3D）Dirac半金属上。通过研究3D Dirac半金属的介电常数的实部，我们确定了入射波长的电介质，ε接近零（ENZ）超材料以及金属区域。有趣的是$s$-和 $p$极化的部分相干光束，在介电和金属区域的反射光束中，GHS的行为完全不同。在GHS的影响下，讨论了诸如空间相干性，入射光束的波长和空间宽度，3D Dirac半金属的温度和厚度等因素。我们可以在狄拉克半金属的这三个区域中产生正负GH偏移，$s$-和 $p$偏振的部分相干光束。
