Harmonic generation in the scattered fields produced by a dielectric sphere coated with time-varying conductive shell is studied using Mie theory approach hybridized conversion matrix methods. Analytic results are derived for plane wave incidence as well general external excitation transition techniques. An equivalent transmission line also discussed. Numerical examples validate expressions thr...

In this article we study a channel with arbitrarily varying channel probability functions in the presence of a noiseless feedback channel (a. v. ch. f.). We determine its capacity by proving a coding theorem and its strong converse. Our proof of the coding theorem is constructive; we give explicitly a coding scheme which performs at any rate below the capacity with an arbitrarily small decoding...
