| Simple tool to evaluate amplitude of spurious responses of filter assemblies caused by out-of-band mismatch. |
| Freeware design tool. Follow steps and design a harmonic (low-pass) corrugated filter online. |
| Freeware design tool. Simulates frequency response for planar (micro-strip, strip-line) structures online. |
| Freeware design tool. Simulates potential spurious spikes or pass-bands caused by high order waveguide modes. |
| Technical note explaining nature of spurious responses of waffle-iron filters. |
| Summary of "fast" semi-numerical and semi-analytical computational method perfect to simulate performance of "practical" filter structures based on metal posts, irises, ridges in different mediums. |
| Quite standard and old approach how to design an H-plane iris filter without software. |
| A generalized version of the previous approach applicable to any kind of direct-coupled filter. A simulator is required here. Following this approach you can build a filter from any kind of junctions like a house from bricks. |
| Similar procedure is applied to quarter-wave-coupled filters. It is a little more sophisticated, but it gives some advantages. |
| A simple multi-moded procedure to test harmonic filters. |
