1'@ use template: Antenna – Waveguide建工程

边界全是expanded

2'@ define material: Matrix定义matrix材料 1 .Epsilon \要先设置成1? .Mue \

.ConstTanDModelOrderEps \

.DispersiveFittingSchemeEps \

.MaximalOrderNthModelFitEps \’=3.6 eps’’=0.02 .ErrorLimitNthModelFitEps \

.DispersiveFittingSchemeMue \

.AddDispersionFittingValueEps \.AddDispersionFittingValueEps \.AddDispersionFittingValueEps \ 3'@ new component: component1新建元件 4@ define brick: component1:Ambient Substrate 5'@ switch working plane

把Ambient的上下面做成pure copper

6'@ pick face am下面

7'@ define material: Copper (pure)材料,铜 1 下一步把cooper 换成IACS 为什么还做这一步 .Type \

Kappa \和sigma有什么区别电导率是kappa .Rho \密度 .ThermalType \

.ThermalConductivity \热导 .HeatCapacity \ 热容量

.MechanicsType \各向同性的选第三个就行

.YoungsModulus \杨氏模量固体材料抵抗形变能力的物理量

Young's modulus E, shear modulus G, bulk modulus K, 和Poisson's ratio ν 之间可以进行换算,公式为:E=2G(1+v)=3K(1-2v) .PoissonsRatio \ 泊松比 .ThermalExpansionRate \热量扩展 .DispModelEps \ .DispModelMue \

.DispersiveFittingSchemeEps \ .DispersiveFittingSchemeMue \ .UseGeneralDispersionEps \ .UseGeneralDispersionMue \

Epsilon \要先设置成1? .Mue \

8'@ make shape from faces: component1:solid1

9'@ pick face am的上面

10'@ make shape from faces: component1:solid2

做导体的中间,和介质上下面的pure copper换为 IACS层

11'@ pick mid point am中点 12'@ align wcs with point放wcs 13'@ move wcs移动了-0.286 14'@ rotate wcsu 270

15'@ define curve polygon: curve1:polygon1导体 16'@ define material: IACS材料lossy metal 1 .Mue \

.Sigma \同样是电导率,但是用的sigma .Colour \

17'@ define coverprofile: component1:solid3曲线做成面 IACS 18'@ thicken sheet: component1:solid3加厚成导体长 19'@ change material: component1:solid1 to: IACS 20'@ change material: component1:solid2 to: IACS

导体下面的TDoxide层

21'@ pick face导体下面

22'@ define material: RDoxide材料 RD氧化物 1 Epsilon \ .Mue \ .Sigma \ .TanD \

.TanDFreq \在10以下损耗角不变 .ConstTanDModelOrderEps\

.DispersiveFittingSchemeEps \

.DispersiveFittingSchemeMue \改不了? .Colour \

23'@ make shape from faces: component1:TRoxide

24'@ thicken sheet: component1:TRoxide\25'@ define background 不用动氧化层的background 26'@ define frequency range 20G

27'@ define boundaries x 是magnetic yz electric别的不用动

修改了matrix的

28'@ define material: Matrixmatrix 2 .DispersiveFittingSchemeEps \ .MaximalOrderNthModelFitEps \

.ErrorLimitNthModelFitEps \ 0.01变为0.002,其余参数相同这个无所谓吧?? .DispersiveFittingSchemeMue \

定义了两个端口

29'@ pick face:Ambient Substrate\30'@ define port: 1 .Xrange \

.Yrange \ .Zrange \ 31'@ pick faceAm \32'@ define port: 2 .Xrange \

.Yrange \ .Zrange \

做导体上面的铜箔层TRfoil

33'@ activate global coordinates local wcs并不是global 34'@ pick mid point导体面的中点:solid3\35'@ align wcs with point

36'@ define curve polygon: curve1:polygon1应该需要把wcs转一下的 .Point \

.LineTo \ .LineTo \ .LineTo \ .LineTo \

37'@ define material: TRfoil铜箔的材料 1 .Epsilon \ .Mue \ .Sigma \

.TanD \损耗正切 .TanDFreq \ .TanDGiven \

.TanDModel \

.ConstTanDModelOrderEps \ ??

.DispersiveFittingSchemeEps \ .DispersiveFittingSchemeMue \.Colour \

38'@ define coverprofile: component1:solid4导体上面的TRfoil

39'@ boolean insert shapes: component1:Ambient Substrate, component1:solid4需要插入到周

围介质(仿真时说有重叠部分)

40'@ thicken sheet: component1:solid4\

改变铜箔材料注意,这里三个define

41'@ define material: TRfoil铜箔 2

.ConstTanDModelOrderEps \把4改成1了

42'@ define material colour: TRfoil这一步不需要,因为没有改动 43'@ define material: TRfoil没有改动

44'@ activate global coordinateslocal wcs

45'@ rename block: component1:solid4 to: component1:TRfoil

把介质下方的IACS变成RDoxiede

46'@ change material: component1:solid1 to: RDoxide 47'@ thicken sheet: component1:solid1\

介质下方的RDoxide下方做IACS 48'@ pick facesolid1\

49'@ make shape from faces: component1:solid4\

介质上层做成TRfoil

50'@ change material: component1:solid2 to: TRfoil

51'@ thicken sheet: component1:solid2\

介质上层TRfoil的上层做成IACS 52'@ pick facesolid2\

53'@ make shape from faces: component1:solid5\

删除端口又重新设置端口? 54'@ delete ports

55'@ pick faceAmbient Substrate\56'@ pick facecomponent1:solid1\57'@ pick facecomponent1:solid2\58'@ define port: 1

59'@ pick faceAmbient Substrate\60'@ pick facecomponent1:solid2\61'@ pick facecomponent1:solid1\62'@ define port: 2

设置网格参数,建网格分组

63 '@ set mesh properties三次设置一样做不了三次,只能一次只是hex 64 '@ set mesh properties可能是因为三个分组,所以设置三次 65 '@ set mesh properties

66'@ create group: meshgroup1添加三个meshgroups分别拖三个item进去 67'@ add items to group: \

68'@ create group: meshgroup2

69'@ add items to group: \70'@ create group: meshgroup3

71'@ add items to group: \

72'@ set local mesh properties for: meshgroup2设置group2, .Set \因数 .Set \

73'@ add items to group: \把solid3拖进group2 74'@ add items to group: \把TRoxide拖进group2

75'@ set local mesh properties for: meshgroup1设置group1 .Set \ .Set \

76'@ add items to group: \把solid3拖进group1

77'@ set local mesh properties for: meshgroup2又重新设置group2 .Set \ .Set \ .Set \

.Set \ .Set \ .Set \ .Set \ .Set \ .Set \

78'@ set mesh properties不知道怎么设,打开后设置的都是下面

打开global properties的第三个

79'@ set mesh properties按平常设置,许多参数不用变,global的第一个

80'@ set local mesh properties for: meshgroup2设置group2 局部网格细化

.Set \

增加fixpoint ??????

81'@ pick end point选择foil 右下角的点

81'@ new absolute fixpoint at (0.17160, -48.92675, 0.019)定点fixpoint list 总是不能选中 83'@ new absolute fixpoint at (0.1716, -48.92675, 0.019)上下有区别吗? 84'@ clear picks

85'@ set mesh properties同78 .RatioLimit \

.LinesPerWavelength \ .MinimumStepNumber \
