A 23-year-old woman presented with constant pendular vertical oscillations in primary gaze along with bilateral horizontal gaze palsy (Video 1) within 3 days of acute pontine hemorrhage (Figure). There was no palatal tremor. Gaze palsy was likely due to involvement of the paramedian pontine reticular formation.

This article presents a substrate integrated coaxial line (SICL)-based low-cost bias tee network operating in K- and Ka-band (20–29 GHz). A butterfly stub is introduced in the direct current (DC) circuit path for the radiofrequency (RF) isolation. A single-layer ceramic capacitor is used along the RF mainline to provide the DC isolation.
