The present application discloses calibration system and method for an electric field probe and a magnetic field probe based on multiple components. The system includes a microstrip line calibration assembly, a clamp, a vector network analyzer and a data processing unit; two groups of microstrip lines included in the microstrip line calibration assembly can be distributed on different routing layers of the same PCB board or on independent PCB boards; the first group of microstrip lines is single microstrip lines or differential lines under common mode excitation, which are used to generate a main component Hof a magnetic field, and the second group of microstrip lines is differential lines under differential mode excitation, which are used to generate a main component Eof an electric field.

A search method is disclosed. The method obtains a plurality of search results for a query based on first relevance scores, and classifies the plurality of search results into a plurality of classifications. Based on respective rankings of the plurality of search results in corresponding classifications of the plurality of classifications, second relevance scores for the plurality of search results are generated, and the plurality of search results are ranked based on the first relevance scores and the second relevance scores. The technique achieves lower consumption of system resources, faster computation speed and more flexibility in diversification of search results.

Search method and system

The present disclosure discloses a search method and system. A method obtains a first search result set of first search results relevant to query data submitted by a client. According to a first relevance score and a preset diversity field of each first search result in the first search result set, a second relevance score of each first search result is calculated. The preset diversity field represents an attribute category of a respective first search result. According to the first relevance score and the second relevance score, a relevance parameter score for each first search result is generated. According to a preset number of second search results and the relevance parameter score, the present number of second search results are extracted from the first search result set to display to the client. The technique achieves lower consumption of system resources, faster computation speed and more flexibility in diversification of search results.

An integrated single-fiber multi-directional transceiver such as a diplexer or triplexer for FTTH applications comprises at least a laser for transmitting a first signal at a first wavelength, a photodetector for receiving a second signal at a second wavelength, and a 2&#xd7;2 optical coupler. The 2&#xd7;2 optical coupler has four ports, of which portconnects to a fiber through an input/output waveguide, portleads to the photodetector through another waveguide, portand portare connected with the gain waveguide and are placed inside the laser cavity. Light emitted by the gain waveguide inside the laser cavity at portof the coupler is partially coupled to portas a feedback for the laser and partially coupled to portwhich couples to the optical fiber to transmit the first signal. On the other hand, the second signal at the second wavelength that is launched into the coupler from the input/output waveguide at portis entirely coupled to portthat leads to the photodetector. The design allows both the transmitted and received signals to be directed to their intended destinations with minimal loss.
