Previously there was no internationally agreed standard for waveguides operating above 330GHz.
The new standard is split into three parts:
- Part 1 (IEEE 1785.1:2012) defines the operating frequencies, dimensions, tolerances and names for the waveguide
- Part 2 (IEEE 1785.2:2016) provides three designs of waveguide interface (flange) to guarantee alignment accuracy
- Part 3 (IEEE 1785.3:2016) describes how to assess the performance of a pair of waveguide interfaces
Dr James Watts, Chief Executive of Flann Microwave, said: “This work will be hugely important in the future as the sub-millimeter bands are increasingly used for communications, security imaging and remote sensing applications. Indeed the previous British Standard, International Electrotechnical Commission and US Mil Standards have remained largely unchanged for 40 years.”
The Flann team has been working with the IEEE Standards working group since it was formed in March 2008, and the interface drawings in the new IEEE standard were produced by Flann mechanical engineers.
