  "abstract": "Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies. Here, an effective Hamiltonian approach is proposed to analyze the complex eigenvalues of scattering systems. By imposing zero scattering constraints (i.e., transmission or reflection zeros) on the Hamiltonian of a two‐mode photonic system, the complex eigenvalues corresponding to transmissionless and reflectionless modes are calculated and it is revealed that the Kerker anomalies are a result of spontaneous parity‐time (PT)‐symmetry‐breaking in the complex plane. This formalism provides a generic method to study non‐Hermitian scattering and offers physical insights into coupled‐mode resonating systems. Furthermore, it provides universal rules for designing photonic devices with unidirectional scattering and full 2π phase modulation.",
