摘要： An electromagnetic wave transmission structure adapted to cause convergence of an electromagnetic wave includes a substrate and a transmission unit provided on the substrate and including an annular metal plate. The annular metal plate has a weighted average inner radius and a weighted average outer radius each related to the wavelength of the electromagnetic wave, the distance between the electromagnetic wave transmission structure and a focal point defined as the point of convergence of the electromagnetic wave, and the distance between the source of the electromagnetic wave and the focal point. The plural inner and outer radii of the annular metal plate have the same trend of variation. Each inner or outer radius corresponds to a weight related to the reference included angle formed between the inner or outer radius and a reference axis.

摘要： A method for deploying an electromagnetic wave guiding structure includes a communication dead zone analysis step and an improvement measure determination step. In the former step, a frequency band in use and an electromagnetic wave signal strength threshold value are preset, and a processing module creates an electromagnetic map for the electromagnetic wave intensity over an area in the frequency band in use based on an electronic map of the area, wherein the electromagnetic map shows a communication dead zone. In the latter step, the processing module obtains an existing electromagnetic wave path according to the electromagnetic map and infers from the existing electromagnetic wave path the installation position and type of at least one electromagnetic wave guiding structure assembly suitable for use to guide the electromagnetic wave to the communication dead zone and ensure that the coverage ratio of the electromagnetic wave in the area reaches a threshold value.
