Reflectionless Filters

When conventional electric filters pass some frequencies, says Morgan, the frequencies that are not passed can bounce around a circuit and create all kinds of havoc--that is the filters do not attenuate stop-bands as advertised, but reflect them. He describes filters that, in principle and given ideal components, have a reflection coefficient that is identically zero at all ports and at all frequencies from zero to infinity--reflectionless filters. Among his topics are passive microwave networks, foundations of reflectionless filters, generalized reflectionless filters, transmission-line reflectionless filters derivation, and tools for advanced topology creation.
