Abstract:
A high frequency electromagnetic field coupled type thin film multilayered electrode, comprising:a plurality of layers of thin film conductors and a plurality of layers of thin film dielectrics alternately stacked to provide a plurality of microwave transmission lines, said microwave transmission lines each comprising a respective pair of said thin film conductors between which corresponding ones of said thin film dielectrics are sandwiched,wherein a respective film thickness of each of said thin film conductors is set so as to be smaller than a skin depth at a predetermined frequency,wherein, based on a number (n) of layers of said thin film conductors and said thin film dielectrics, the respective film thickness of each of said thin film dielectrics is set so that, at the predetermined frequency, respective phase velocities of microwaves which propagate through at least two of said plurality of microwave transmission lines are substantially equal to each other, andwherein, based on the number (n) of layers of said thin film conductors and said thin film dielectrics, the respective film thickness of each of said thin film conductors is set so that electromagnetic fields of at least two of said plurality of microwave transmission lines are coupled with each other and currents flowing in respective ones of said thin film conductors are substantially equal to each other.
