Abstract
Stacked, multilayer substrate integrated waveguide (SIW) components are discussed in this contribution. The superordinate design constraint is the limitation of the lateral dimensions determined by the width of the feed SIWs. This is achieved by using a broadband adjoined SIW-to-folded-SIW transition. Based on it, a Riblet-type short-slot quadrature hybrid coupler and a helix-like layer twist of two stacked SIWs are designed, manufactured, and validated in K-/Ka-band by measurements.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
