给我用matlab对法拉第波做可视化的matlab代码

以下是用 MATLAB 对法拉第波做可视化的代码：

% 设置参数
L = 1; % 波导长度
a = .1; % 波导宽度
b = .2; % 波导高度
n = 50; % 离散点数
dx = L / n; % 离散步长
dy = a / n; % 离散步长
dz = b / n; % 离散步长
c = 3e8; % 光速
f = 10e9; % 频率
lambda = c / f; % 波长
k = 2 * pi / lambda; % 波数
omega = 2 * pi * f; % 角频率
mu = pi * 4e-7; % 真空磁导率
epsilon = 8.854e-12; % 真空介电常数
eta = sqrt(mu / epsilon); % 真空阻抗

% 初始化场分量
Ex = zeros(n, n, n);
Ey = zeros(n, n, n);
Ez = zeros(n, n, n);
Hx = zeros(n, n, n);
Hy = zeros(n, n, n);
Hz = zeros(n, n, n);

% 计算场分量
for i = 1:n
for j = 1:n
for k = 1:n
x = (i - .5) * dx;
y = (j - .5) * dy;
z = (k - .5) * dz;
r = sqrt(x^2 + y^2 + z^2);
theta = atan2(y, x);
phi = atan2(sqrt(x^2 + y^2), z);
kx = k * sin(phi) * cos(theta);
ky = k * sin(phi) * sin(theta);
kz = k * cos(phi);
if kx == && ky ==
Ex(i, j, k) = ;
Ey(i, j, k) = ;
Ez(i, j, k) = ;
Hx(i, j, k) = ;
Hy(i, j, k) = ;
Hz(i, j, k) = ;
else
Ex(i, j, k) = -1j * omega * mu / kx * Hy(i, j, k);
Ey(i, j, k) = 1j * omega * mu / ky * Hx(i, j, k);
Ez(i, j, k) = ;
Hx(i, j, k) = -1j * omega * epsilon / kx * Ey(i, j, k);
Hy(i, j, k) = 1j * omega * epsilon / ky * Ex(i, j, k);
Hz(i, j, k) = ;
end
end
end
end
