[0043] The novel deep neural network automatic modeling method proposed by the invention can be applied to the modeling and design of various microwave devices, such as parametric modeling of microwave filters, electromagnetic optimization design of antennas, and transistor modeling. In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiment of the present invention (waveguide filter modeling) will be described in detail below with reference to the accompanying drawings.
[0044] like figure 1 As shown, the present invention proposes a novel hybrid deep neural network structure comprising a BN layer and a Sigmoid hidden layer. Using this structure for image 3 When modeling the waveguide filter shown, the input variable x of the deep neural network is the geometric parameter h of the filter 1 , h 2 , h 3 , h c1 , h c2 and frequency ω, denoted as x=[h 1 h 2 h 3 h c1 h c2 ω] T ; output variable y is S 11 The rea
