Spin waves (SWs) are promising information carriers for beyond-CMOS technologies owing to their wave-based, Joule-heating-free signal transmission and inherent phase degree of freedom. Inline SW interference devices, where counter-propagating waves interfere along a single propagation axis, offer compact and scalable logic architectures. While previous studies addressed amplitude imbalance arising from SW non-reciprocity [1], dynamic and energy-efficient phase reconfiguration remains challenging [2]. Here, we report an inline SW interference device integrated with electric-field-induced phase modulation applied selectively to the +k propagation path. This approach enables low-power, reversible control of the interference condition without altering excitation frequency or geometry, allowing programmable switching between logic states (XOR and XNOR). Our results demonstrate an energy-efficient, reconfigurable magnonic logic platform suitable for on-chip wave-based computing.
