Abstract:
The theory of excitation of magnetostatic forward volume waves (MSFVW) with a microstrip transmission line was developed for the case, when microstrip is placed at some distance from the ferrite film surface. A technique is described for computing the impedance (both the reactance and radiation resistance) per unit length of a microstrip transmission line. The dependence of this impedance on the spacing between the microstrip and ferrite film has been studied for the case of magnetostatic forward volume waves. It has been found that smaller values of this spacing cause increase the frequency range of effective MSFVW excitation. Experimental and theoretical results are in excellent agreement for radiation resistance of microstrip transducers.
