Speed and performance of the ADE method. Repeat Problem 10.8 using the ADE method. Is the same result achieved? How do the simulation times compare?

Problem 10.8

Submarine communication. Consider the problem of communication between two submarines submersed at some depth at sea, 1 km from each other. Seawater can be modeled as a Debye material with parameters dc = 81, = 1, and t0 = 10-5 s. Analyze the problem at hand using the recursive convolution method and make recommendations as to how best to proceed. A critical parameter to determine is the pulse rate, which determines the data rate. In other words, what is the minimum separation between successive pulses? What is the highest data rate (number of pulses per second) which can be used? Assume 2D TMz propagation between the submarines and vertical electric antennas (i.e., excite the z field at the transmitting submarine and also monitor the z field at the receiving submarine) and that the transmitted Gaussian pulses can have a peak initial electric field value of 1 V/m. Also assume that the receiving system is designed to recognize a peak signal value of 0.5 mV/m or more as a one, whereas a value of 0.05 mV/m or less is recognized as a zero
