请问当采用UPML计算时，同轴圆柱的计算参数的设置时下面哪种对呀？
第一种，不考虑ex,ey,ez,hx,hy,hz的在YEE网格上的变化
for i=15:36
for j=1:jh_tot
for k=1:kh_tot
if ((j-js)^2+(k-ks)^2)<=4

C1ex(i,j,k)=C1(2);
C2ex(i,j,k)=C2(2);
C3ex(i,j,k)=C3(2);
C4ex(i,j,k)=C4(2);
C5ex(i,j,k)=C5(2);
C6ex(i,j,k)=C6(2);

C1ey(i,j,k)=C1(2);
C2ey(i,j,k)=C2(2);
C3ey(i,j,k)=C3(2);
C4ey(i,j,k)=C4(2);
C5ey(i,j,k)=C5(2);
C6ey(i,j,k)=C6(2);

C1ez(i,j,k)=C1(2);
C2ez(i,j,k)=C2(2);
C3ez(i,j,k)=C3(2);
C4ez(i,j,k)=C4(2);
C5ez(i,j,k)=C5(2);
C6ez(i,j,k)=C6(2);

D1hx(i,j,k)=D1(2);
D2hx(i,j,k)=D2(2);
D3hx(i,j,k)=D3(2);
D4hx(i,j,k)=D4(2);
D5hx(i,j,k)=D5(2);
D6hx(i,j,k)=D6(2);

D1hy(i,j,k)=D1(2);
D2hy(i,j,k)=D2(2);
D3hy(i,j,k)=D3(2);
D4hy(i,j,k)=D4(2);
D5hy(i,j,k)=D5(2);
D6hy(i,j,k)=D6(2);

D1hz(i,j,k)=D1(2);
D2hz(i,j,k)=D2(2);
D3hz(i,j,k)=D3(2);
D4hz(i,j,k)=D4(2);
D5hz(i,j,k)=D5(2);
D6hz(i,j,k)=D6(2);
end
end
end
end
第二种是考虑yee网格上ex,ey,ez,hx,hy,hz的结构上的不同
for i=15:36
for j=1:jh_tot
for k=1:kh_tot
if ((j-js+0.5)^2+(k-ks)^2)<=4     %ey有半个网格之差
C1ey(i,j,k)=C1(2);
C2ey(i,j,k)=C2(2);
C3ey(i,j,k)=C3(2);
C4ey(i,j,k)=C4(2);
C5ey(i,j,k)=C5(2);
C6ey(i,j,k)=C6(2);
end
if ((j-js)^2+(k-ks+0.5)^2)<=4
C1ez(i,j,k)=C1(2);
C2ez(i,j,k)=C2(2);
C3ez(i,j,k)=C3(2);
C4ez(i,j,k)=C4(2);
C5ez(i,j,k)=C5(2);
C6ez(i,j,k)=C6(2);
end
if ((j-js+0.5)^2+(k-ks+0.5)^2)<=4
D1hx(i,j,k)=D1(2);
D2hx(i,j,k)=D2(2);
D3hx(i,j,k)=D3(2);
D4hx(i,j,k)=D4(2);
D5hx(i,j,k)=D5(2);
D6hx(i,j,k)=D6(2);
end
end
end
end
for i=15+1:36+1       ex有1个网格之差
for j=1:jh_tot
for k=1:kh_tot
if ((j-js)^2+(k-ks)^2)<=4
C1ex(i,j,k)=C1(2);
C2ex(i,j,k)=C2(2);
C3ex(i,j,k)=C3(2);
C4ex(i,j,k)=C4(2);
C5ex(i,j,k)=C5(2);
C6ex(i,j,k)=C6(2);
end
if ((j-js+0.5)^2+(k-ks)^2)<=4
D1hz(i,j,k)=D1(2);
D2hz(i,j,k)=D2(2);
D3hz(i,j,k)=D3(2);
D4hz(i,j,k)=D4(2);
D5hz(i,j,k)=D5(2);
D6hz(i,j,k)=D6(2);
end
if ((j-js)^2+(k-ks-0.5)^2)<=4

D1hy(i,j,k)=D1(2);
D2hy(i,j,k)=D2(2);
D3hy(i,j,k)=D3(2);
