Technical Issues - Designs on Multiple Substrates

DESIGN 2.61.0317 adds Edit...Reverse Segment to the Groups Mode design editor. This helps users combine designs onto one or more substrates. While designs can also be reversed in the Design Macro editor, it may be more intuitive to do so in the Groups Mode editor.

This section reviews a technique for combining multiple designs. Both entrance medium (AIR) and exit medium (SUB) have index 1.0. Previously designed Lowpass and Highpass filters are opened in the Groups Mode macro editor as shown here. When treated as a normal one-side design, the H layer will be next to the glass substrate.

Effectively the design is deposited onto AIR and the substrate is treated as a massive layer.

The sequence for combining designs is shown below.

1. Starting design is 2G (2 mm glass).
2. Insert Lowpass design before 2G with Macro...Insert 1 (<Shift+F1>).
3. Insert Highpass design after 2G with Macro...Insert 2 (<Shift+F2>).
4. Lowpass is backwards! Highlight the stack and click Edit...Reverse Segment (<Ctrl+S>).
5. Final design now has the Lowpass outer H layer adjacent to glass.
