| Multiphysical phenomena are neither new nor rear, it started with human beings. Basically
multiphysics is interdisciplinary term and originate with collaboration of various research
fields. Multiphysical phenomena exist in both form either naturally or manmade in nature.
We breathe in a multiphysics world. Our real life processes from morning to evening are
inherently multiphysics. From electron to atom, atom to galaxies and from amino acid to
living organisms, naturally they interlinked with various physical phenomena which is
operating at different spatial and temporal scale. Subjected loads and across deformations
on solids, fluidstructure interactions, complex flows, plasma and chemical processes, and
electromagnetic and thermomechanical system are just a few representative examples of
multiphysics in fundamental and applied sciences.
Split Plane and Vertical Interconnect Accses both creating discontinuity on PCBs surface.
Any signal line passes over disconuity point must faces signal integrity Problem. Return
current facing problem due to theses diconutity. In this thesis author modifing the proposed
model of Mukhtar[18] based split model to make signal integrity better and analysing the
Via discontinuity and their electrical modelling. Bus-Bar used in PCBs to provide the pwer
connection to devices are analysed using comsol multiphysics tool.
