Configuration of MARS


E Field Distribution in MARS Oven (DI-Water 25degC)


Relationship of Permittivity of DI-Water withTemperature


Permittivity of Water VS Temperature (at 2.45GHz)


Measurements of the Precursor Solution at various Temperature (e’)


Measurements of the Precursor Solution at various Temperature (e’’)

Extrapolation of permittivity of Precursor Solution at 175degC


Permittivity of the precursor and DI-water


E Field Distribution of MARS-5(separate pictures)


Comparison of E Field maxima


Discussion

Given other same conditions

  • E field at middle plane of the reactor is higher than the bottom

  • E field for precursor is lower than water (due to higher loss tangent of precursor)

  • For water, temperature goes up -> loss tangent goes down -> E field goes up

  • For precursor, temperature goes up -> loss tangent goes up -> E field goes down

  • For MARS-5 oven, E field maxima for 33mm reactor is lower than 11mm reactor
