Abstract
The complex admittivity of a network of resistors and capacitors is calculated at pc on a square lattice using a transfer matrix. The loss tangent shows a region of anomalous frequency scaling, with t=s. Finite-size scaling reveals two crossover frequencies, as expected from duality.Keywords
