Updates to the Chu-Harrington Limit

Electrically small antennas are commonly benchmarked against the Chu limit. However, applying the Chu circuit model to analyze the Q of high order spherical modes leads to scenarios with both large Q-factors and wide bandwidths, which is clearly unphysical. This contradiction brings into question the circuit model's validity for lower order modes, as well as all subsequent work that is consistent with Chu's result. At the conference we will present our updates to the Chu-Harrington limit.
