The updated workshop pages were mainly tested on Internet Explorer 11 and Google Chrome (version 85). A brief functional check was also carried out on the latest versions of Microsoft Edge and Mazilla Firefox. It was noted that newer versions of browsers (Chrome, Firefox, Edge) performed calculations and simulations much faster.
Design Process Updates
A new low-pass filter synthesis method based on impedance matching of a weakly irregular ("quasi-periodic") corrugated waveguide with an input / output interface through a quarter-wave transformer (related links [1,2]). The new synthesis method generally leads to better matching results.
User Interface Updates
The old methods of displaying the graphs of the filter characteristics are replaced by new ones with better resolution and image quality.
Data Input and Output
Although the old methods of input and output of design and s-parameters remain unchanged, some data formats are already obsolete (old version of HFSS and AutoCAD). In the updated workshop, the user is invited to use the function of transferring the design to the new design studio "WR - Connect 2020", which has more diverse methods for designing waveguide filters, more convenient ways to save project files and translate them into new versions of Ansoft / ANSYS HFSS. It is proposed to use this workshop in the initial design stage only, then transfer the design to WR - Connect 2020 and finalize it there.
