Introduction This introduction is not part of IEEE Std 1785.1-2012, IEEE Standard for Rectangular Metallic Waveguides and Their Interfa
7、ces for Frequencies of 110 GHz and AbovePart 1: Frequency Bands and Waveguide Dimensions. IEEE Std 1785.1-2012 is the first standard in a series of three IEEE standards that will provide the agreed reference for all organizations using rectangular metallic waveguides at frequencies of 110 GHz and ab
8、ove. This series of standards will enable efficient trade between customers and suppliers, and common design criteria and practices for component, systems, and design engineers. The three IEEE 1785 standards (Parts 1, 2, and 3) are described briefly as follows: IEEE Std 1785.1 (i.e., this publicatio
9、n) describes the frequency bands and aperture dimensions of the waveguides. IEEE P1785.2 (to be published separately) will describe the waveguide interfaces. IEEE P1785.3 (to be published separately) will give recommendations for performance and uncertainty specifications for the combined waveguide
10、apertures and interfaces. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations.

40、ry: Glossary of Terms & Definitions should be consulted for terms not defined in this clause.3General requirements and definitions 4.Standardized types 4.1The series of rectangular metallic waveguides covered by this standard shall be as defined in Table 1. The series of waveguides can be extended t
41、o derive waveguides sizes for use at frequencies above those given in Table 1 (i.e., for waveguides with smaller dimensions). The process to achieve this is described in 5.3 of this standard. The ratio of the broad wall dimension (width) to the narrow wall dimension (height) for all waveguides cover

45、 Type designation 4.2For waveguides in this standard, the type designation shall be comprised of a) The label WM. The letter W indicates that the label refers to Waveguide. The letter M indicates that the waveguide is specified using Metric dimensions. b) A number characterizing the particular size
46、of the waveguide. This number corresponds to the width of the waveguide, specified in micrometers (i.e., m). For example, WM-570 refers to rectangular metallic waveguide of width 570 m. Since the ratio of the waveguide width to height is 2:1, the height is (570 2) m = 285 m. Equivalence to waveguide
47、s in other standards 4.3Waveguides shown in the unshaded region of Table 1 have a direct equivalence to waveguides given in other standards (IEC 60153-2, 1974, and MIL-DTL-85/3C, 2005). The dimensions of these waveguides are essentially the same as those given in these other standards, but their spe
48、cified recommended frequency ranges can be slightly different. These differences are due to different methods used in each standard to determine the recommended frequency ranges for the waveguides. Table 2 shows the equivalence between the type designations used in this standard and the other standa
49、rds (IEC 60153-2, 1974, and MIL-DTL-85/3C, 2005). Frequencies 5.Cut-off frequency 5.1The cut-off frequency, fc, for the dominant mode for each waveguide listed in Table 1 is calculated using acf21rc= where c = speed of electromagnetic waves in vacuum (defined as 299 792 458 m/s) r= relative permittivity, assumed equal to unity in this standard4a = waveguide broad wall dimension (m)54For a given application, more precise values of cut-off frequency can be calculated using values of rappropriate for the dielectric filling the waveguid
