field.java

该内容是关于fdtd的源码,我用过,ok!不错!

public class Component
{
	private int imat;
	public double xl, xu, yl, yu, zl, zu;
    private double time_appear;
    public double time;
//    private boolean exists;
    public Component(int imat, double xl, double xu,
    double yl, double yu, double zl, double zu, double time_appear)
    {
		this.imat=imat;
		this.xl=xl;
		this.xu=xu;

		this.zu=zu;
		this.time_appear=time_appear;
    }


	public boolean exists(double time)
	{

		{
//			this.exists=true;
			return true;
	    }
	    else

	}

    public void setImat(int imat)
    {
