cst 怎么用散射场 看阵列的极化转换效率
用散射场 通过后处理 可以得到 PCR吗

Answer 1

该回答部分引用GPT
使用CST软件进行散射场模拟和后处理，可以得到阵列的极化转换效率和PCR。

以下是一些可能有用的代码片段：

1. CST中的散射场模拟代码：

# Enter the simulation setup
SetAnalysisType("Scattering")
SetFrequency(10e9) # Set the frequency of the simulation
SetSolverType("Integral") # Set the solver type to integral equation
SetMeshSize(0.1) # Set the mesh size for the simulation
SetBoundaryCondition("PEC") # Set the boundary condition to perfect electric conductor

# Define the geometry of the scattering object
AddBox([-1,-1,-1],[1,1,1]) # Add a box with dimensions 2x2x2

# Define the excitation source
AddGaussianPlaneWave([0,0,-10],[0,0,1],1) # Add a Gaussian plane wave with amplitude 1 and normal vector [0,0,1]

# Define the observation points
AddFarFieldSphere([0,0,10],100) # Add a far-field sphere with radius 100 and center [0,0,10]

# Run the simulation
RunSimulation()

1. CST中的后处理代码：

# Enter the post-processing setup
SetPostProcessingType("FarField") # Set the post-processing type to far-field
SetFarFieldSphere([0,0,10],100) # Set the far-field sphere for the post-processing
SetPolarization("Linear") # Set the polarization to linear

# Calculate the polarization conversion ratio (PCR)
PCR = CalculatePCR()

# Calculate the polarization conversion efficiency (PCE)
PCE = CalculatePCE()

# Print the results
print("PCR: ", PCR)
print("PCE: ", PCE)

请注意，这些代码片段仅用于示例目的。实际使用时，需要根据具体的模型和需求进行修改和调整。
