<p>Dear Kawshik,<\/p><p>Thank you for contacting us!<\/p><p>If I understand correctly, this is a substrate with etched material in pyramid shape. This means that the material of the pyramids is air. If this is the case then you can create a new structure group where you will define the substrate by inserting a rectangle and an array of pyramids. The material of the pyramids should be set to etch.<\/p><p>An example of such a structure group is the following:<\/p><p><\/p><p>The x_span and y_span parameters are the x and y length of the base of each pyramid. The z_span is the pyramid height. The x_period and y_period is the number of pyramids in the x and y direction.<\/p><p>The x_span_rect, y_span_rect and z_span_rect are the dimensions of the substrate.<\/p><p>After inserting these parameters in the “Properties” tab, you can add the following script in the “Script” tab:<\/p><p> <\/p><p>deleteall;<\/p><p>for (i=1:y_period) {<\/p><p>  for (j=1:x_period) {<\/p><p>    addpyramid;<\/p><p>    set(“x”,(x_span\/2)+(j-1)*x_span-x_period*x_span\/2);<\/p><p>   set(“y”,(y_span\/2)+(i-1)*y_span-y_period*y_span\/2);<\/p><p>   set(“x span bottom”,x_span);<\/p><p>   set(“x span top”,0);<\/p><p>   set(“y span bottom”,y_span);<\/p><p>   set(“y span top”,0);<\/p><p>   set(“z span”,z_span);<\/p><p>   set(“material”,”etch”);<\/p><p>  }<\/p><p>}<\/p><p>addrect;<\/p><p>set(“x span”,x_span_rect);<\/p><p>set(“y span”,y_span_rect);<\/p><p>set(“z min”,-z_span\/2);<\/p><p>set(“z max”,-z_span\/2+z_span_rect);<\/p><p> <\/p><p>You can also add an index monitor to check the results.<\/p><p> <\/p><p>Best Regards,<\/p><p>Afroditi<\/p><\/p>\n","protected":false},"template":"","class_list":["post-343604","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
