Abstract

Even when at least one of a capacitor (C) connected to a main loop and a capacitor (C) connected to an amplification loop cannot be set to an optimal value, a current value of a current (I) flowing on the amplification loop can be made sufficiently large by setting the capacitors (C, C) based on any of an optimal Ccurved line, an optimal Ccurved line, and an optimal Cstraight line that pass through an optimal point (C, C) of the capacitors (C, C) and extend along a ridge of contour lines each joining the points where the magnitude of the current (I) is equal on a diagram showing a relation of values of the capacitors (C, C) with the magnitude of the current (I).
