materialstructure.java

该内容是关于fdtd的源码,我用过,ok!不错!

//package fdtd;

public class MaterialStructure
{
	public int imat;
	public double xl, xu, yl, yu, zl, zu;
    public double time_appear;
    public double time_disappear;
    public double time;

    public Component(int imat, double xl, double xu,
    double yl, double yu, double zl, double zu, double time_appear, double time_disappear)
    {
		this.imat=imat;
		this.xl=xl;
		this.xu=xu;
		this.yl=yl;
		this.yu=yu;
		this.zl=zl;
		this.zu=zu;
		this.time_appear=time_appear;
		this.time_disappear=time_disappear;
    }


	public boolean exists(double time)
	{
		if ((time>=this.time_appear)&&(time<this.time_disappear))
		{
			return true;
	    }
	    else
	    {
			return false;
		}
	}


	public boolean in(double x, double y, double z)
	{
		boolean temp;
		temp=false;
		if (x>=this.xl)
		{ if (x<this.xu)
		  { if (y>=this.yl)
		    { if (y<this.yu)
			  { if (z>=this.zl)
				{ if (z<this.zu) temp=true;
				}
			  }
			}
	      }
	    }
		return temp;
	}


	public boolean intime(double x, double y, double z, double time)
	{
		return (in(x,y,z)&&exists(time));

	}

}
