“…The coaxial-strip transitions at ports 2 and 4 were removed, since they did not provide the no-load mode at these ports. The shown scheme is all-pass at the same phase velocities of in-phase and antiphase waves [32,33] The measurement scheme shown in Figure 11 allows measuring the voltage of the reflected wave from port 1. This dependence was measured.…”

An analogy is drawn between the appearance of tsunami waves and "slow" waves in coupled structures (CS). Tectonic disturbances, as the cause of tsunami generation, generate "fast" waves similar to those in СS. The assumption is made that it is theoretically possible to give a rapid prediction of the occurrence of a natural disaster on the basis of information about the disturbing factor and environmental parameters. The paper notes the obvious problem of the lack of information about the parameters of the initial conditions of excitation of a rapid wave of tectonic origin in the prediction of tsunamis. It is possible that the considered electrodynamics analogy "Tsunami" will allow, firstly, to put and solve the problem of reconstruction of disturbing impact parameters, since the information about it comes before consequences, secondly, to develop "desktop" model of tsunami for some areas, thirdly, to develop measures to protect the coast by creating devices for diversion of tsunami wave energy part in safe directions.
