Abstract：To set up the theoretical calculation method for impedance of spheres in sizes,we put forward the calculation formula 6 ρ/πd(ρ and d represent sphere material resistivity and diameter,respectively),which indicated that the numerical value of impedance was in inverse proportion to the diameter.We detected three sorts of microsphere and found that the bigger the size was,the smaller the value of impedance would be.Our conclusion manifested high similarity to the theoretical results.This study would provide a mathematical formula to calculate the theoretical impedance values of different sizes impedance coding microspheres.
