Microwave resonator magnetic field measuring device and magnetic field measuring method

A microwave resonator magnetic field measuring device (1) for measuring alternating magnetic fields, comprising:

• a base plate (11) with at least one support/bearing/clamping point (111);
• at least one mechanical oscillator (12+13) formed as a microwave resonator in the form of a cantilever (13) having at least one magnetostrictive layer (12), the latter being connected and mounted at at least one point to the base plate (11) in the at least one supporting/bearing/clamping point (111),
• at least one coupling means (161) for microwaves and
• at least one decoupling means (162) for microwaves,
• wherein the base plate (11) and the mechanical oscillator (12+13) formed as a microwave resonator are at least partly electrically conductive and electrically conductively connected to one another,
• wherein a tuning screw (17) and/or an adjustable reactance (171) and/or a geometry adjustment for detuning the mechanical oscillator (12+13) designed as a microwave resonator is provided in the base plate (11).
