The penetration of the magnetic field in a network consisting of the superconducting grains and intergranular region depends not only on the applied external magnetic field but also on the underlying pinning force density and fraction of the superconducting grains in the sample. Considering the underlying pinning force density in the form of the repetitive Gaussian (RG) nature we have solved the critical state model to get the spatial internal field profile at a particular time instant. The internal magnetic field as a function of the position inside the superconductor exhibits nonlinear, step-like nature. The complicated nature of the penetration of the field gets strongly affected by the size of the granular region and the total pinning force density in the superconductors. We have numerically calculated the real and imaginary parts of the complex susceptibility. The variation of the imaginary part with the temperature has a peak at a temperature which shifts towards the higher temperature with the reduction of the superconducting fraction.

磁场在由超导晶粒和晶间区域组成的网络中的渗透不仅取决于所施加的外部磁场，还取决于样品中潜在的钉扎力密度和超导晶粒的分数。考虑到重复的高斯（RG）性质形式的潜在钉扎力密度，我们已经解决了临界状态模型，以便在特定时刻获得空间内部磁场分布。作为超导体内部位置的函数的内部磁场表现出非线性的，阶梯状的性质。场穿透的复杂性质受到颗粒区域的大小和超导体中总钉扎力密度的强烈影响。我们已经通过数值计算了复杂磁化率的实部和虚部。虚部随温度的变化在一个温度处具有一个峰值，该温度随着超导分数的减小而向较高温度移动。
