Claim Text:
1. An electromagnetic resonance coupler comprising: a first layer including a first principal surface and a second principal surface opposite to the first principal surface, the first layer having a first dielectric constant and a first dielectric dissipation factor; a second layer facing the first principal surface of the first layer, the second layer having a second dielectric constant higher than the first dielectric constant and a second dielectric dissipation factor lower than the first dielectric constant; a third layer facing the second principal surface of the first layer, the third layer having a third dielectric constant higher than the first dielectric constant and a third dielectric dissipation factor lower than the first dielectric constant; a first resonator located between the first layer and the second layer, the first resonator having a planar shape; and a second resonator located between the first layer and the third layer, the second resonator having a planar shape.
