    what is full wave analysis?

    Oops! I meant to say "in static the time derivative terms in Maxwell's equations are set to zero. In quasi-static, the wave propagation terms are instantatious (a good approximation if the bounding box is smaller than the wavelength of the highest frequency of interest). In full-wave, the wave...

    what is full wave analysis?

    Full-wave is best defined by contrast to static and quasi-static methods. Static means simplifying Maxwell's equations such that there is no coupling at all between E and B fields: ε div(E)= ρ curl(B)=µ J With quasi-static, one form of coupling between B and E is considered: the E field...

    Meaning of "Quasi Static"

    Static means simplifying Maxwell's equations such that there is no coupling at all between E and B fields: ε div(E)= ρ curl(B)=µ J With quasi-static, one form of coupling between B and E is considered: the E field generates conventional current in conductive materials (Ohms Law) and then this...

    HP HFSS or ANSOFT HFSS?

    price details of hfss Agilent reentered the 3D EM market with EMDS. EMDS uses the finite element method like Ansoft HFSS uses and the now obsolete HP HFSS used to use. You can run your EMDS license either standalone, OR integrated into ADS. https://www.agilent.com/find/eesof-emds
