Claim 0:
1. A transmission instrument comprising:
at least one first wave source configured to transmit at least one first wave, which includes plural different frequency components in at least one direction including a direction different from a propagation direction in a multi-dimensional space, to at least one point of interest within at least one of an observation object, a medium, a second wave source, and a propagating second wave generated by said second wave source, and thereby generate at least one third wave, which is a band-widened and sidelobe-reduced wave in said at least one direction and which includes at least one of a frequency-increased component and a frequency-decreased component in said at least one direction, as a result of generation of at least one of (i) a higher or lower harmonic tone wave due to an effect of exponentiation or multiplication of the same frequency component, and (ii) a chord or different tone wave due to an effect of multiplication of plural different frequency components, depending on a nonlinear effect generated in said at least one point of interest and corresponding to exponentiation or multiplication,
wherein said at least one third wave has at least one new property that cannot be directly obtained by a single wave generation or a superposition of plural waves with respect to at least one of a wave intensity, focusing, a propagation direction, a steering angle, a crossing angle of plural waves, a waveform in a propagation direction or a direction different therefrom, a beam shape, a frequency in a propagation direction or a direction different therefrom, a bandwidth in a propagation direction or a direction different therefrom, and an intensity ratio of a main-lobe to a side-lobe or a grading lobe.
