| 摘要 |
A microwave cavity resonator useful in electron paramagnetic resonance spectrometers made from a printed circuit board having an electrically conductive surface printed on one side thereof and folded so as to form a plurality of the walls of a parallelepipedon cavity resonator, the conductive surface of the circuit board forming the inner conductive surfaces of the cavity. Modulation coils formed by printed circuit techniques on the other side of the circuit board serve as field modulation coils for the cavity resonator, the conductive inner wall surfaces aligned with said coils being made pervious to enhance penetration of the modulation field into the cavity resonator. |
