Abstract: A generalized dispersion equation is derived featuring coupled mode theory, parity-time (PT) symmetry, and leaky wave antennas of arbitrary periodic modulation. It can be specialized to each ...

Reflect the shape in the line \(x = -1\). The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the ...
