A variety of influencing factors of temperature control accuracy are discussed. Moreover  for these error factors  improvement measures are given to reduce the nonlinear error. Finally  circuit parameter error is quantified to propose a calculation method for margin of error in a temperature control system.

In this paper  fractal Y aperture FSS has been designed using recursive technology and the periodic method of moments(PMoM) is employed to characterize the transmission properties of FSS as band-pass filters. The frequency response to the structure parameters when electromagnetic wave incident with different angles and polarizations is discussed and the numerical analysis show good correlation to the measured results. 2010 IEEE.
