The design of high frequency resonant circuits is difficult because it requires the calculation of ac resistance of an inductor. The inductor suffers from skin effect and proximity effect and hence its ac resistance increases with frequency. The inductor is therefore multi stranded to minimize the ac resistance and multilayered to increase the inductance. This paper presents a method of calculating the ac resistance. The model used in the paper also takes care of the eddy current reaction field. Experimental results confirm the effectivity of the calculation method.
