This　paper　provides　an　overview　of　the　recent　advances　of　electromagnetic　(EM)　centric　multiphysics　(MP)　optimization　of　microwave　components.　A　novel　parallel　EM　centric　multi-physics　optimization　(MPO)　technique　is　introduced.　The　pole-residue-based　transfer　function　is　exploited　to　build　an　effective　and　robust　surrogate　model.　Multiple　EM　centric　MP　evaluations　are　performed　in　parallel　to　generate　the　training　samples　for　establishing　the　surrogate　model.　The　developed　surrogate　model　can　be　valid　in　a　relatively　large　neighborhood　which　makes　an　effective　and　large　optimization　update　in　each　optimization　iteration.　This　technique　takes　a　small　number　of　iterations　to　obtain　the　optimal　EM　centric　MP　response.　©　2020　IEEE.
